MK2069-04GI - 160MHz VCXO Clock Translator | Renesas
MPN： MK2069-04GI ✓ 啟用中MK2069-04GI 概覽
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.

典型應用
MK2069-04GI 適用於 6 應用s: Telecom Frame-Clock Translation, Network Interface Clocking, Communications Equipment Clock Conditioning, Test and Measurement Clocking, Embedded Processor Clock Translation, Industrial Data Acquisition.
Telecom Frame-Clock Translation
The MK2069-04GI fits telecom equipment that must translate a reference clock into a different service or line-card clock. Its VCXO-based PLL architecture uses selectable reference and feedback dividers, while the phase detector can operate down to 8 kHz or lower. That low operating point directly supports clock systems whose frequencies share a low common denominator, including the 8 kHz frame clock cited in the Renesas datasheet. The PLL corrects frequency and phase error while the LVCMOS output provides a convenient digital clock for downstream logic. Designers must select dividers that remain within the documented PLL range and verify lock behavior with the actual input slew rate and output loading.
推薦
Network Interface Clocking
The MK2069-04GI can provide a programmable local clock for network-interface and communications subsystems that cannot derive the required frequency by ordinary integer division. Its PLL compares divided reference and feedback signals and corrects the VCXO output to reduce phase error, producing a stable LVCMOS clock up to 160 MHz. This is useful when the board receives a clean reference but several subsystems require a different, precisely related frequency. The design should verify input-jitter attenuation under the selected loop settings and ensure the output driver has adequate margin for the PCB load and downstream clock receiver.
推薦
Communications Equipment Clock Conditioning
The MK2069-04GI is suitable for communications equipment that requires a low-jitter clock translated from an external reference. The on-chip VCXO and PLL can correct phase and frequency differences, and the verified specifications indicate that the device can attenuate jitter carried by the input clock. With an LVCMOS interface and operation up to 160 MHz, it supports digital clocking blocks in line cards, baseband processors, and interface controllers. Engineers should review the PLL operating limits for the selected ratio, preserve clean supply and reference routing, and validate the final jitter and lock performance under production temperature and load conditions.
推薦
Test and Measurement Clocking
The MK2069-04GI can supply a programmable LVCMOS clock in test and measurement instruments that synthesize or condition timing for ADC, DAC, and digital subsystems. The VCXO-based PLL architecture supports conversion from a stable external reference to a required output frequency, including ratios that are awkward for a simple integer divider. Maximum output frequency is 160 MHz, so the device is appropriate for moderate-speed digital timing rather than the highest RF synthesis rates. The board should provide controlled reference routing, adequate decoupling, and a conservative output termination arrangement to preserve deterministic edge quality during measurement.
推薦
Embedded Processor Clock Translation
The MK2069-04GI can translate an external board reference into the clock required by a processor, FPGA, or communications controller when their frequencies do not share a simple integer relationship. Its PLL and selectable dividers allow the generated clock to be tuned while phase correction reduces accumulated timing error. The LVCMOS interface and 160 MHz ceiling align with many embedded clock domains, although the exact device must be checked against the required operating range. Designers should validate startup and lock behavior, ensure the reference meets minimum slew requirements, and avoid routing the sensitive clock through noisy power-regulator areas.
推薦
Industrial Data Acquisition
The MK2069-04GI is applicable to industrial acquisition equipment that needs a stable local clock derived from a shared factory reference. By translating the input through the VCXO and PLL, the device can provide a phase-corrected LVCMOS clock for sampling, serial communication, and control subsystems. This can simplify synchronization across modules that consume the same reference but require different operating frequencies. The implementation must include clean supply decoupling, controlled clock routing, and validation over the full industrial temperature range. Input and output loading should also be checked because clock slew and edge degradation can affect acquisition timing even when the PLL remains locked.

主要差異化特點
- Supports low-common-denominator clock translation (對比MK2069-04GITR)
- Provides PLL-based phase correction rather than fixed-ratio division (對比MK2069-04GITR)
- Uses a single LVCMOS clock-output path (對比MK2069-04GITR)
設計說明
Keep the reference input and clock output away from switching-regulator power paths, high-current return routes, and digital signals with fast edges. Provide the input slew rate and source impedance required by the Renesas datasheet. Because the PLL measures phase through divider paths, routing asymmetry can add static phase error or reduce jitter margin even when frequency lock is achieved.
Place the required bypass capacitors immediately adjacent to the supply and ground pins, and provide a low-impedance ground reference. The verified snippets do not state the supply voltage, capacitor values, or layout details, so those requirements must be taken from the manufacturer datasheet. Confirm the selected supply supports the full 160 MHz operating range and the required PLL divider combinations before releasing the PCB.
Do not assume that any 160 MHz clock translator is a drop-in replacement for the MK2069-04GI. The required 56-TFSOP footprint must be accompanied by matching pin functions, control logic, divider behavior, input thresholds, output drive, and supply limits. Validate lock range, startup, jitter, and phase accuracy on hardware using the intended reference clock and final receiver load.
Terminate the reference and output nets according to the datasheet and the receiver characteristics rather than applying an arbitrary resistor value. Check output rise and fall time under the expected PCB load, avoid excessive stub lengths, and maintain a continuous return plane under clock routes. These controls are important because poor edge quality can degrade the apparent jitter even when the PLL itself remains locked.
合規資訊
Compliance data was not present in the verified snippets. AEC-Q100 is treated as not applicable because this is a clock-and-timing IC rather than an automotive-qualified claim, but no automotive qualification is asserted.
