345R-62LF

Clock Generators, PLLs, Frequency Synthesizers Overview

The ICS345R-62LF is a field-programmable clock synthesizer from Renesas Electronics, part of the VersaClock family. It generates up to nine high-quality, high-frequency clock outputs from a single low-frequency crystal or clock input. The device features a triple PLL architecture and LVCMOS outputs with a maximum frequency of 200MHz. It operates on a 3.15V to 3.45V supply voltage within an industrial temperature range of 0°C to 70°C. Packaged in a 20-SSOP format, it replaces discrete crystals and oscillators in electronic designs requiring precise timing.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '62LF' against the official Renesas datasheet to confirm package type and temperature grade. Ensure the ordering code matches the required RoHS compliance status and tape-and-reel or tube packaging options available for this specific variant.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a design requires multiple synchronized clock outputs derived from a single reference source. Confirm that the LVCMOS output swing meets the input requirements of downstream logic devices. Verify that the 20-pin SSOP footprint fits the PCB layout constraints compared to alternative packages like QSOP.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the ICS345 VersaClock series, designed to simplify timing architectures by integrating multiple synthesizers into a single programmable IC. It serves as a direct replacement for fixed-frequency crystal oscillators, reducing bill-of-materials count and board space in complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Check for pin-compatible alternatives within the VersaClock family if different output counts or voltage levels are needed. Verify that any substitute maintains the same 200MHz maximum frequency and LVCMOS output characteristics.
