MK2069-01GI - 160MHz VCXO Clock Synchronizer | Renesas
MPN： MK2069-01GI ✓ 啟用中MK2069-01GI 概覽
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.

典型應用
MK2069-01GI 適用於 6 應用s: Telecommunications Line-Card Clocking, Jitter-Attenuated Clock Distribution, Selectable Reference-Frequency Systems, Frequency Translation and Multiplication, Communication Infrastructure Equipment, Instrumentation and Test Equipment.
Telecommunications Line-Card Clocking
The MK2069-01GI fits line cards that must distribute a stable reference while selecting among multiple upstream sources. Its VCXO-based architecture supports system synchronization, jitter attenuation, and frequency translation, while the verified maximum frequency of 160 MHz covers demanding communication timing planes. The three-input multiplexer allows a system to change reference selection without changing the PCB, although the asynchronous, non-latched control behavior must be coordinated in system firmware or hardware logic. Use the 3.15 V to 3.45 V supply range as a firm design constraint and preserve the manufacturer's recommended grounding and external-component layout.
推薦
Jitter-Attenuated Clock Distribution
The MK2069-01GI is appropriate when a clock network must reduce timing variation while retaining a selectable reference. Its stated jitter-attenuation function provides a reason to place the device between unstable or independently sourced references and downstream circuitry, and the 160 MHz maximum frequency supports high-speed communication clocks. Because detailed jitter limits were not included in the supplied source excerpts, engineers must obtain the current Renesas datasheet and verify RMS or peak jitter under the intended frequency, output-divider, and crystal-network conditions before using the device in a compliance-sensitive link.
推薦
Selectable Reference-Frequency Systems
The three-reference-input multiplexer makes the MK2069-01GI useful in equipment that must operate from more than one external timing source. ICLK0 and ICLK1 provide disclosed 5 V tolerance, allowing compatible source signaling without exceeding those input limits, while the device core remains powered from 3.15 V to 3.45 V. Control pins are asynchronous and non-latched, so the receiving system must ensure that source transitions do not create unacceptable clock disturbances. Validate every source's voltage, slew rate, duty cycle, and stability against the manufacturer timing diagrams.
推薦
Frequency Translation and Multiplication
The MK2069-01GI supports frequency multiplication or translation, allowing a system to derive useful clock outputs from a selected reference rather than providing every frequency with separate oscillators. Its maximum stated frequency of 160 MHz makes it relevant to equipment requiring conversion of a lower reference into higher-rate communications timing. The actual synthesis ratios, lock behavior, output accuracy, and jitter must be taken from the current datasheet because those values were not exposed in the supplied search results. PCB users should reproduce the reference design closely to preserve phase noise and startup performance.
推薦
Communication Infrastructure Equipment
The MK2069-01GI can support communications infrastructure equipment that needs centralized synchronization, reference switching, and low-jitter distribution in a compact surface-mount implementation. Its 56-TFSOP package provides 56 electrical connections for mixed signal and control functions, while the disclosed -40 °C to 85 °C range suits many industrial and telecom environments. Designers should avoid placing noisy switching supplies or high-current digital return paths beneath sensitive timing nodes. The component's mixed analog and digital architecture makes component placement, reference grounding, and return-path discipline as important as the logic connection diagram.
推薦
Instrumentation and Test Equipment
The MK2069-01GI is suitable as a reference-synchronization element in instrumentation that accepts external timing sources and needs repeatable clock distribution. A selectable three-reference arrangement can improve laboratory usability by allowing equipment to operate with different external standards. The 160 MHz maximum frequency covers fast sampling, communications, and digital backplane timing, but the final design must confirm output jitter and frequency accuracy for the selected divider configuration. Keep the VCXO loop components close to the device and isolate noisy analog and power sections to avoid degrading phase performance.

- Integrated three-source reference selection (對比MK2069-01GILFTR)
設計說明
Follow the Renesas reference layout closely because the manufacturer identifies the MK2069-01 as sensitive to PCB layout and external component selection. Place the VCXO-loop components in the positions and orientation shown by the datasheet, minimize sensitive-node capacitance, and avoid routing clocks beside high-current switching paths. Treat component tolerances and parasitics as part of the timing network rather than as independent selection details.
Operate the core supply only within the verified 3.15 V to 3.45 V range. ICLK0 and ICLK1 are 5 V tolerant, but that tolerance applies to those reference inputs and does not expand the allowable supply range for the device or ICLK2. Provide local supply decoupling with short return paths and verify ripple at the pins because supply disturbance can degrade clock quality even when average voltage is correct.
Keep the asynchronous multiplexer controls away from long sensitive clock routes, and account for the fact that the selection inputs are asynchronous and non-latched. Any reference change can be observed without an internal latch action, so the surrounding system should sequence changes safely. Review the input-mux selection table and associated timing diagrams in the current manufacturer datasheet before defining system control behavior.
Validate output jitter, duty cycle, rise time, fall time, and drive capability under the intended output configuration rather than relying only on the 160 MHz headline frequency. The supplied data does not include detailed output specifications, so bench measurements and the current datasheet are required. Maintain a continuous ground reference beneath the 56-TFSOP and route high-speed differential outputs as a controlled pair with matched impedance.
