SY87700VHH

Application Specific Clock/Timing Overview

The SY87700VHH is a Clock and Data Recovery (CDR) integrated circuit manufactured by Microchip Technology, operating within the AnyRate family. It supports data rates from 32Mbps to 175Mbps NRZ streams with selectable 3.3V or 5V power supplies. The device features two on-chip PLLs for clock generation and recovery, utilizing differential PECL high-speed serial I/O. It is housed in a 32-pin EPAD-TQFP package and includes link fault indication and ECL-compatible I/O.

Application Specific Clock/Timing Feature Summary

• Supports clock and data recovery for NRZ data streams ranging from 32Mbps to 175Mbps
• Features two on-chip PLLs: one for clock generation and another for clock recovery
• Compatible with SONET/SDH/ATM standards including OC-1, OC-3, FDDI, and Fast Ethernet
• Includes built-in line receiver inputs requiring no external buffering

Application Specific Clock/Timing Applications

• SONET/SDH/ATM systems (OC-1, OC-3)
• Fast Ethernet applications
• Proprietary architectures up to 175Mbps

Application Specific Clock/Timing Procurement Notes

Verify component authenticity through authorized channels as the SY87700VHH is a specialized industrial IC. Confirm that the specific ordering suffix corresponds to the Pb-Free 32-pin EPAD-TQFP package variant. Ensure compliance with humidity sensitivity levels and storage temperature limits during handling.

Application Specific Clock/Timing Selection Notes

Select the SY87700VHH when designing systems requiring flexible frequency selection between 32Mbps and 175Mbps. This model is suitable for both 3.3V and 5V logic environments. For new designs, verify thermal requirements against the 32-pin EPAD-TQFP package specifications to ensure adequate heat dissipation.

Application Specific Clock/Timing Part Context

The SY87700VHH belongs to the SY87700V series of clock recovery devices originally developed by Micrel, Inc., which was later acquired by Microchip Technology. It serves as a complete solution for retiming serial data streams in high-speed transmission systems.
