VSC8479YY

Overview

The VSC8479YY is a telecommunications transceiver manufactured by Microchip Technology. It operates as a 1:16 and 16:1 transceiver with integrated clock and data recovery (CDR) and clock multiplier unit (CMU). The device supports I2C and SPI interfaces for control. It requires a 1.8V supply voltage and functions within a temperature range of -5°C to 90°C. The component is housed in a 244-BBGA, FCBGA package measuring 17x17 mm. It is classified as a surface mount device with one circuit channel.

Feature Summary

• Integrates clock and data recovery functionality
• Includes built-in clock multiplier unit
• Supports standard serial communication protocols

Applications

• Telecommunications interface systems
• Network infrastructure equipment
• Signal transmission modules

Procurement Notes

Verify the specific suffix 'YYY' against the manufacturer's official datasheet to confirm pinout and electrical characteristics match system requirements. Ensure compatibility with the required 1.8V power domain and thermal management specifications for the operating environment. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a single-channel transceiver with integrated CDR and CMU is required for telecom applications. Consider the 244-FCBGA package size for PCB layout constraints. Verify that the I2C and SPI interface capabilities align with the host controller's available communication lines. Check the operating temperature range suitability for the intended deployment environment.

Part Context

This part belongs to the VSC8479 series from Microchip Technology, designed for high-performance telecommunications interfaces. It is distinct from other series like SG1843Y or SY88973VMG which serve different functions such as switching controllers or amplifiers. The VSC8479 family focuses on signal integrity and clock recovery in network hardware.
