SY87700ALZG-TR

Application Specific Clock/Timing Overview

The SY87700ALZG-TR is a low-power, 3.3V AnyRate Clock and Data Recovery (CDR) integrated circuit manufactured by Microchip Technology. It supports data rates from 32Mbps to 208Mbps for NRZ streams. The device features two on-chip PLLs: one for clock recovery and another for clock generation. It operates within an industrial temperature range of –40°C to +85°C and utilizes a 28-pin SOIC package with NiPdAu lead finish. The part number suffix -TR indicates tube packaging.

Application Specific Clock/Timing Feature Summary

• Clock and data recovery from 32Mbps up to 208Mbps NRZ data stream
• Two on-chip PLLs: one for clock generation and another for clock recovery
• Selectable reference frequencies via FREQSEL pins
• Differential PECL high-speed serial I/O

Application Specific Clock/Timing Applications

• SONET/SDH/ATM OC-1 and OC-3
• Fast Ethernet, SMPTE 259
• Proprietary architecture up to 208Mbps

Application Specific Clock/Timing Procurement Notes

Verify the ordering suffix -TR corresponds to tube packaging as specified in the datasheet. Confirm the component meets RoHS requirements and check for any specific humidity sensitivity classifications before procurement.

Application Specific Clock/Timing Selection Notes

Ensure the application requires data rates between 32Mbps and 208Mbps. Verify that the 28-pin SOIC package is suitable for the design, noting it is not recommended for new designs per the manufacturer's guidelines.

Application Specific Clock/Timing Part Context

The SY87700ALZG-TR belongs to the SY87700AL series of low-power CDRs. It is designed for high-speed data transmission systems requiring precise clock recovery and retiming capabilities.

Application Specific Clock/Timing Replacement Considerations
