SY87721LHY

Application Specific Clock/Timing Overview

The SY87721LHY is a Clock and Timer IC manufactured by Microchip Technology, belonging to the SY87721L series. It functions as a 3.2V Any-Rate Clock Data Recovery (CDR) device capable of handling data rates from 28 Mbps to 2.7 Gbps. The component is housed in a TQFP-64 surface-mount package and operates within a standard commercial temperature range. This integrated circuit is designed for timing support applications requiring flexible clock recovery across high-speed serial interfaces.

Application Specific Clock/Timing Feature Summary

• Supports any-rate clock data recovery with a frequency range of 28 Mbps to 2.7 Gbps
• Operates on a single 3.2V power supply
• Available in a TQFP-64 SMD/SMT package

Application Specific Clock/Timing Applications

• High-speed serial communication systems
• Clock recovery in network infrastructure equipment
• Timing support for digital signal processing interfaces

Application Specific Clock/Timing Procurement Notes

The SY87721LHY is listed as a discontinued product by the manufacturer. Distribution availability is currently restricted, with some suppliers indicating no sales in specific regions. Verification of current stock status and end-of-life management options is required before procurement planning.

Application Specific Clock/Timing Selection Notes

Select this component when a fixed-rate CDR is insufficient for variable bit-rate signals up to 2.7 Gbps. Ensure the design environment supports a 3.2V supply voltage. The TQFP-64 package requires appropriate PCB footprint considerations for thermal dissipation and moisture sensitivity management during assembly.

Application Specific Clock/Timing Part Context

This part belongs to the SY87721L family of clock support products from Microchip Technology. It shares the TQFP-64 form factor with other devices in the broader SY89xx and SY877xx series, though functional specifications such as input/output types and operating frequencies vary significantly between specific model numbers.

Application Specific Clock/Timing Replacement Considerations

As the SY87721LHY is discontinued, direct replacements must be sourced from Microchip's current portfolio or qualified third-party equivalents. Verify that alternative components support the same 28 Mbps to 2.7 Gbps any-rate CDR functionality and compatible 3.2V operation.
