MK2069-04GI

Overview

The MK2069-04 is a VCXO-based universal clock translator manufactured by IDT, now part of Renesas Electronics. It features two cascaded PLLs: a VCXO PLL for jitter attenuation and frequency translation using an external pullable crystal (8–27 MHz), and a Translator PLL for output generation up to 160 MHz. The device accepts input clocks from <1 kHz to 170 MHz and produces outputs from 500 kHz to 160 MHz. Configuration is pin-selected without power-up programming. It operates on a single 3.3 V supply with a 5 V tolerant input and includes a lock detector output.

Feature Summary

• VCXO-based architecture provides jitter attenuation and low phase noise generation
• Supports complex frequency translation between standards such as T1/E1 and OC-3/T1
• Pin-selectable configuration for all major PLL divider functions
• Includes PLL lock status output and clear function for rapid phase synchronization

Applications

• Telecom network synchronization (e.g., T1 to E1 translation)
• Video standard conversion (e.g., CCIR-601 to SMPTE 274M)
• High-performance computing clock distribution
• Industrial control systems requiring precise timing

Procurement Notes

Verify the manufacturer designation, as the component was originally produced by IDT before its acquisition by Renesas. Confirm the package type is 56-pin TSSOP. Check for lead-free compliance if required by current environmental regulations, noting that non-green parts may have reached end-of-life status.

Selection Notes

Select this device when jitter attenuation and wide-range frequency translation are required. Ensure the application can accommodate the external loop filter components (RS, CS, CP) and the specific quartz crystal parameters. Verify that the input clock frequency falls within the 1 kHz to 170 MHz range and that the system design supports the necessary pin configurations for the desired divider ratios.

Part Context

This component belongs to the family of VCXO-based clock translators designed for high-precision timing applications. It serves as a bridge between different clock frequency standards, offering flexibility through user-configurable dividers. The device integrates both analog VCXO circuits and digital PLL logic to achieve stable clock synthesis.

Replacement Considerations

Direct replacements should be sought among other VCXO-based clock translators from Renesas or IDT product lines. Verify compatibility regarding pinout, package dimensions (56-pin TSSOP), and electrical specifications such as supply voltage and frequency ranges.
