MK2049-36SI

MK2049-36SI - 3.3V PLL Clock Synthesizer | Renesas

Renesas Electronics MK2049-36SI is a 3.3 V PLL-based communications clock synthesizer that accepts multiple input frequencies and generates T1, E1, T3, E3, OC3 and other communications clock frequencies. The device uses an 8 kHz reference clock, produces LVCMOS outputs, and supports frequencies up to 77.76 MHz. It is supplied in a 20-pin SOIC package. The 3.3 V supply requirement, phase-locked-loop architecture and communications-oriented output range make the MK2049-36SI suitable for line-card, transmission, switching and other telecommunications clocking systems. A PLL clock synthesizer is a clock-and-timing integrated circuit that multiplies or divides a stable reference frequency while locking its internal oscillator to that reference. In the product hierarchy, a PLL synthesizer is a clock generator, a clock-and-timing IC and ultimately a semiconductor. Compared with a free-running oscillator, the phase-locked architecture allows multiple related output frequencies to share a common 8 kHz reference, reducing frequency drift between clocks and simplifying synchronization across a communications system. The MK2049-36 family provides one PLL-based clock-synthesis circuit with a maximum reported output frequency of 77.76 MHz. Its input and output signal format is LVCMOS, and the specified input-to-output ratio shown in the verified distributor listing is 1:3. The SI ordering suffix identifies the industrial 20-pin SOIC configuration. These characteristics make exact timing, supply-voltage and pin-level verification against the Renesas datasheet essential before replacing another PLL clock generator. The verified datasheet guidance states that the MK2049-36 requires only a small number of external components for proper operation. Decoupling capacitors of 0.01 µF should be connected between VDD and GND close to the device, particularly at pins 4 and 7 and at pins 15 and 17. The Renesas document also recommends 33 Ω series terminating resistors on clock outputs when traces exceed one inch and the characteristic impedance is assumed to be 50 Ω. These details minimize supply coupling and high-frequency clock-edge reflections. Typical applications include telecommunications line equipment, T1 and E1 interface systems, OC3 and E3 clock generation, Gigabit Ethernet clock-distribution networks, and legacy synchronous communications equipment. In these systems, the 3.3 V operating supply and LVCMOS interfaces simplify integration with compatible digital logic. The shared 8 kHz reference allows several output rates to remain phase-related, which is valuable when transmitters, switches, serializers and test equipment must operate coherently. Designers should preserve the manufacturer's recommended 0.01 µF decoupling layout and account for output drive requirements when the clock net is not properly terminated. The 33 Ω source-termination guidance is especially important for long PCB traces or cable connections because excessive edge reflections can degrade timing margin and produce spurious clock activity. Supply sequencing, crystal or oscillator startup behavior, and the exact configuration of each programmable output should be checked in the full datasheet. This product page consolidates the verified manufacturer and distributor information, identifies the documented external-component requirements, and distinguishes true same-package alternatives from redesign-level options. It also provides application-focused design guidance for engineers evaluating the MK2049-36SI as a legacy or production communications clock-synthesis component.

MK2049-45ASI

MK2049-45ASI - 51.84MHz Dual-PLL Clock Synth | Renesas

Renesas Electronics MK2049-45ASI is a 51.84 MHz maximum-frequency dual phase-locked-loop clock synthesizer in a 20-pin SOIC package. It operates from a 3.3 V communications-clock supply and provides one clock-output circuit with a stated input-to-output ratio of 1:3. The device is designed for frequency synthesis and jitter attenuation in communications clock systems. A phase-locked-loop clock synthesizer belongs to the clock and timing IC hierarchy, where it sits below clock-generation and frequency-synthesis functions. It locks an internal oscillator to a reference clock and then generates or divides reference-derived frequencies. Unlike a free-running oscillator, a PLL-based device can transfer frequency stability from an external reference while allowing output frequency synthesis, programmable division, and jitter attenuation. The MK2049-45ASI contains two PLL functions. According to the Renesas MK2049-45 datasheet, the first PLL is VCXO-based and uses a pullable crystal to track signal wander and attenuate input jitter. The second PLL supports frequency synthesis. A maximum output frequency of 51.84 MHz and a 1:3 input-to-output ratio identify the device as a communications-clock generation solution rather than a general-purpose timer. The device accepts a clock reference and produces a clock output without differential signaling. Its architecture is intended to support communications equipment that needs a stable, derived clock while limiting reference jitter. The 3.3 V supply designation also places the device in systems designed around low-voltage digital clock trees, provided the complete power, input, output, and decoupling requirements are followed from the manufacturer datasheet. Typical applications include communication line-card clocking, telecom backplane clock distribution, network-interface clock synthesis, and other systems requiring a PLL-derived communications reference. The maximum 51.84 MHz output makes it particularly relevant to designs operating below that frequency while using a stable external reference and controlled division ratio. When designing a board around the MK2049-45ASI, use the manufacturer pin-description table and recommended external-component values before finalizing the layout. Pay particular attention to clock-input routing, pullable-crystal implementation, output loading, supply decoupling, and unused-pin handling, because incorrect clock topology can undermine otherwise correct PLL operation. This product summary organizes the device architecture, package information, verified drop-in candidates, parameter comparisons, and practical clock-design guidance into a format that helps engineers evaluate the MK2049-45ASI before beginning a communications-clock schematic.

Clock generators and PLLs are members of the clock and timing IC hierarchy, while the MK2058-01SI specializes in conditioning an existing reference. Its VCXO-based architecture combines an oscillator with a phase-locked loop to attenuate jitter inherited from the incoming source or interconnect path. The verified feature set includes one clock channel, a 27 MHz maximum frequency, LVCMOS-compatible input and output signaling, and a 2:1 input-to-output division ratio. The single-ended architecture means that neither the input nor the output is differential.

It accepts an 8 kHz frame-rate reference clock and phase-locks its generated output to that reference, producing common telecommunications clock frequencies. A voltage-controlled crystal oscillator-based clock translator is a clock-generation IC that combines frequency translation, phase locking, and reference synchronization. It belongs to the broader clock and timing IC hierarchy, where clock generators and phase-locked loops support communication networks, digital transport systems, and other equipment requiring stable, traceable timing references. Unlike a free-running oscillator, the MK2059-01SI derives its output from an external reference, improving synchronization across a telecommunications system. Key features include a 25.92 MHz maximum output frequency, an input-to-output ratio of 2:1, LVCMOS input and output signaling, and an integrated PLL. The supply-voltage range is 3.15 V to 3.45 V, while the rated operating-temperature range is -40°C to +85°C. The surface-mount 20-SOIC package provides a compact option for communication and timing equipment. Internally, the device uses a VCXO-based architecture and PLL-based clock generation to lock the generated clock to the 8 kHz input reference. This phase-locked relationship is the principal technical feature: the output is not intended as an unrelated free-running oscillator but as a translated reference derived from the incoming frame clock. The PLL feature and LVCMOS interfaces place the device in the class of integrated frequency translators intended for telecommunications clocking.

It accepts an 8 kHz frame-rate reference clock and phase-locks its generated output to that reference, producing common telecommunications clock frequencies. A voltage-controlled crystal oscillator-based clock translator is a clock-generation IC that combines frequency translation, phase locking, and reference synchronization. It belongs to the broader clock and timing IC hierarchy, where clock generators and phase-locked loops support communication networks, digital transport systems, and other equipment requiring stable, traceable timing references. Unlike a free-running oscillator, the MK2059-01SITR derives its output from an external reference, improving synchronization across a telecommunications system. Key features include a 25.92 MHz maximum output frequency, an input-to-output ratio of 2:1, LVCMOS input and output signaling, and an integrated PLL. The supply-voltage range is 3.15 V to 3.45 V, while the rated operating-temperature range is -40°C to +85°C. The surface-mount 20-SOIC package provides a compact option for communication and timing equipment. Internally, the device uses a VCXO-based architecture and PLL-based clock generation to lock the generated clock to the 8 kHz input reference.

MK2069-01GI

MK2069-01GI - 160MHz VCXO Clock Synchronizer | Renesas

The Renesas Electronics MK2069-01GI is a VCXO-based line-card clock synchronizer with a maximum stated frequency of 160 MHz, a 3.15 V to 3.45 V supply range, and a 56-pin thin TSSOP package measuring 0.240 inch, or 6.10 mm, in width. It combines system synchronization, jitter attenuation, and frequency multiplication or translation in one mixed analog and digital timing IC. A clock synchronizer is a timing integrated circuit that coordinates one or more clock domains by selecting reference inputs and distributing or conditioning clock signals. The MK2069-01GI belongs to the broader clock generator, PLL, and frequency synthesizer category, where its VCXO architecture provides a variable-frequency reference that can be controlled to support synchronization and output-frequency conversion. The principal verified features include a 160 MHz maximum clock frequency, three alternate reference inputs, an asynchronous input multiplexer, and LVCMOS differential outputs. ICLK0 and ICLK1 are 5 V tolerant according to the manufacturer datasheet, while the remaining reference inputs do not share that stated tolerance. The device is intended for surface mounting in a 56-TFSOP package and operates over the disclosed -40 °C to 85 °C range. The MK2069-01 uses a VCXO-based architecture to deliver the performance expected of a canned VCXO-based hybrid timing device at a lower cost. Its mixed analog and digital implementation makes PCB layout and external component selection especially important. Short, controlled routing, suitable grounding, and compliant external crystal-network components are necessary to preserve timing performance and stability. Typical uses include line-card clock synchronization, telecommunications equipment, communication infrastructure, frequency translation, and jitter-sensitive clock distribution. A 160 MHz ceiling makes the device relevant to systems that distribute a common reference while requiring selectable reference sources or attenuated clock paths. Designers should treat the 3.15 V to 3.45 V supply range as a hard constraint and should not infer 5 V operation merely because ICLK0 and ICLK1 are 5 V tolerant. The input multiplexer selection is asynchronous and non-latched, so control timing and switching behavior should be evaluated against the system requirements. Exact power consumption, jitter limits, output configurations, and full pin assignments require confirmation from the manufacturer datasheet before layout release. This product record combines verified manufacturer and distributor information with package-specific engineering guidance, sourcing context, and candid identification of parameters that still require design-in verification.

The Renesas Electronics MK2069-04GI is a VCXO-based universal clock translator with a maximum operating frequency of 160 MHz, PLL-based clock generation, and LVCMOS input/output interfaces. It is packaged in a 56-TFSOP package measuring approximately 6.10 mm in width. The device is intended for translating clock frequencies between systems whose clocks do not share a convenient direct integer relationship. A VCXO-based clock translator is a clock-generation and timing-management device that uses a voltage-controlled crystal oscillator and phase-locked loop architecture. In the broader semiconductor hierarchy, it belongs to the clock and timing IC category, where PLL-based translators condition, multiply, divide, or otherwise redistribute reference-clock energy. The MK2069-04GI provides a single LVCMOS clock output path and uses selectable reference and feedback dividers to establish the translation ratio. Key features include support for frequencies up to 160 MHz, PLL operation, LVCMOS signal compatibility, and user-selectable divider ranges. The on-chip VCXO produces a stable, low-jitter output clock using a phase detector frequency down to 8 kHz or lower. This architecture is useful for telecom frame clocks, including standards operating from an 8 kHz common clock, and for other systems requiring clock conversion between unrelated frequencies. The PLL phase detector, reference divider, feedback divider, and VCXO work together to correct phase and frequency errors between the incoming reference and the generated output. Divider selection determines the effective multiplication ratio, while the output stage delivers the resulting clock in LVCMOS form. The device also provides jitter attenuation of the input clock and can accept low input frequencies, making it useful where conventional integer-ratio clock trees are insufficient. Typical applications include telecom line-card clock translation, network interface clocking, communications equipment, test and measurement systems, and embedded systems that need a locally generated clock with low jitter. The part can also support clock-domain adaptation where the source and destination frequencies have a low common denominator. In each case, the design must select divider values compatible with the PLL operating range and preserve the required output-to-input phase relationship. Designers should verify the reference and feedback divider combinations, input slew rate, output loading, and loop stability against the manufacturer datasheet. The 56-TFSOP footprint requires adequate board area and careful routing of clock inputs and power supplies. Decoupling close to the supply pins and a controlled source impedance are important for maintaining predictable phase noise and jitter performance. This product summary consolidates distributor availability information, manufacturer-based clock architecture details, replacement guidance, and practical implementation considerations into a design-oriented reference for engineers evaluating the MK2069-04GI.

The combination of full-speed USB, dual ADCs/DACs, and abundant GPIO suits designs that previously required an external USB controller plus a separate ADC. Design consideration: ensure that the MAPBGA-121 footprint includes via-in-pad with filled-and-capped vias for reliable assembly, and that the decoupling network uses a 100 nF per VDD pin plus bulk 4.7 uF tantalum capacitors for ADC reference noise. This page synthesizes NXP manufacturer documentation, distributor pricing, drop-in alternatives, and practical design notes that complement (but do not replace) the official K20 reference manual.
