SY87721LHY-TR

Application Specific Clock/Timing Overview

The SY87721LHY-TR is a clock data recovery (CDR) device from Microchip Technology, designed for high-speed serial communication applications. It operates within a supply voltage range of 3.15V to 3.45V and supports data rates from 28 Mbps to 2.7 Gbps. The component utilizes an LVDS protocol and is housed in a 64-TQFP-EP package with dimensions of 10x10 mm. It functions reliably across an industrial temperature range of -40°C to +85°C. This integrated circuit serves as a timing support product, facilitating signal integrity in high-bandwidth digital systems.

Application Specific Clock/Timing Feature Summary

• Supports any-rate CDR functionality for data rates between 28 Mbps and 2.7 Gbps
• Operates on a single 3.3V power supply (3.15V ~ 3.45V)
• Housed in a 64-pin Thin Quad Flat Package with Exposed Pad (TQFP-EP)
• Industrial operating temperature range from -40°C to +85°C

Application Specific Clock/Timing Applications

• High-speed serial link receivers requiring clock recovery
• Telecommunications equipment utilizing LVDS interfaces
• Data acquisition systems processing signals up to 2.7 Gbps

Application Specific Clock/Timing Procurement Notes

The SY87721LHY-TR variant indicates tape-and-reel packaging, distinct from the tray-packaged SY87721LHY. Verify the suffix against official Microchip documentation to confirm packaging differences. Note that the base model SY87721LHY is listed as obsolete in some distributor records; confirm current production status and availability directly with the manufacturer or authorized channels before procurement planning.

Application Specific Clock/Timing Selection Notes

Select this component when designing systems requiring a CDR solution for LVDS signals within the 28 Mbps to 2.7 Gbps range. Ensure the design accommodates the 64-TQFP-EP footprint and thermal requirements associated with the exposed pad. Confirm that the application environment stays within the specified -40°C to +85°C temperature limits and that the power supply remains stable between 3.15V and 3.45V.

Application Specific Clock/Timing Part Context

This part belongs to the SY87721L series of clock and timer ICs manufactured by Microchip Technology. The series includes variants such as the SY87725LHY, which shares similar packaging but targets specific data rates like 2.5 Gbps. The SY87721LHY-TR specifically denotes the reel-packaged version of the SY87721LHY, intended for automated surface-mount assembly processes.

Application Specific Clock/Timing Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate other members of the SY87721L family or newer Microchip CDR products for compatibility, ensuring pinout and electrical specifications match the original design requirements.
