The 252M-55LF is a dual-output, field-programmable clock synthesizer manufactured by Renesas Electronics Corporation. It generates two output frequencies ranging from 314 kHz to 200 MHz using an external crystal or oscillator input. The device supports flexible frequency synthesis for timing applications and is housed in a standard surface-mount package suitable for PCB integration.
Verify component status as the 252M-55LF is listed as obsolete and no longer manufactured by Renesas. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with recommended substitute part numbers before procurement planning.
Select this component only if legacy design compatibility is required. Evaluate alternative modern clock synthesizers for new designs due to obsolescence. Verify pinout and electrical specifications against current system requirements before integration.
The 252M-55LF belongs to the ICS252 series of clock synthesizers. This family provides low-cost, programmable solutions for generating precise clock signals in digital systems. The device is designed for applications requiring stable frequency outputs derived from a single reference source.
The MFR recommends the 5L35021B-000NDGI as a substitute part number. Verify functional equivalence and pin compatibility before replacement.
