345R-65LFT

Clock Generators, PLLs, Frequency Synthesizers Overview

The ICS345R-65LFT 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 operates within a supply voltage range of 3.15V to 3.45V. It supports LVCMOS output logic levels and functions at frequencies up to 200MHz. Designed for surface mount installation, it is housed in a 20-pin SSOP package with a width of 3.90mm. The component operates reliably within a commercial temperature range of 0°C to 70°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '65LFT' against official Renesas documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides genuine components with traceability. Check for moisture sensitivity level (MSL) requirements if storage conditions exceed manufacturer limits. Confirm that the 20-SSOP package dimensions match the target PCB footprint exactly.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single clock source must drive multiple downstream devices requiring different frequencies. Verify that the required output frequencies fall within the 200MHz maximum limit. Ensure the system power supply remains stable between 3.15V and 3.45V. Consider the 0°C to 70°C operating temperature range against the environmental conditions of the final application.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The ICS345R-65LFT belongs to the ICS345 series of VersaClock synthesizers. This series is designed to simplify board design by reducing the number of passive components needed for clock generation. It serves as an alternative to using multiple individual crystal oscillators, thereby saving space and potentially reducing jitter compared to discrete solutions.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements should be sought from the same ICS345 series with identical package and suffix codes. Cross-referencing with other VersaClock models requires careful verification of pin compatibility and output drive strength. Do not assume functional equivalence with generic clock generators due to specific programming requirements.
