VSC7223EV

Overview

The VSC7223EV is a 4-channel unidirectional adaptive channel extender from Microchip Technology, designed for signal integrity applications. It supports data rates up to 16 Gbps and operates on a single 1.2 V supply. The device integrates input equalization, clock and data recovery (CRU), and output de-emphasis to compensate for cable, copper, and backplane losses. Key electrical parameters include a maximum data rate of 16 Gbps, an operating temperature range of -40 °C to 90 °C, and a power dissipation capability within the specified thermal limits. It utilizes a 5 mm x 9 mm 48-pin QFN package.

Feature Summary

• Supports data rates up to 16 Gbps with retimer and re-driver modes
• Integrates Clock and Data Recovery (CRU) using an on-chip frequency synthesizer
• Provides greater than 30 dB of input line equalization and up to 18 dB of programmable output de-emphasis
• Includes built-in VScope™ input signal monitoring technology

Applications

• Compensation for FR-4 traces exceeding 65 inches at 10 Gbps
• Extension of SFP+ copper direct-attached cables (24AWG) beyond 15 meters at 10 Gbps
• Signal conditioning for GE PHY and 10GE PHY interfaces
• Backplane and copper media receiver/driver environments

Procurement Notes

Verify the specific suffix 'EV' against the manufacturer's official documentation to confirm if it denotes a specific evaluation board variant or a standard production package revision. Ensure the component source matches the Microchip Technology datasheet specifications for the VSC7223 series. Confirm RoHS compliance status through the official product page or certified distributor declarations prior to procurement.

Selection Notes

Select the VSC7223EV when system design requires adaptive channel extension for signals up to 16 Gbps in unidirectional paths. It is suitable for applications needing significant input equalization (>30 dB) and programmable de-emphasis (up to 18 dB). Consider this device for environments where low power consumption and compact 48-pin QFN packaging are critical constraints.

Part Context

The VSC7223 belongs to the VSC722x family of adaptive channel extenders manufactured by Microchip Technology. This family focuses on improving signal integrity in high-speed serial links by mitigating insertion loss in copper interconnects. The VSC7223 specifically targets 4-lane configurations, offering a balance between performance and power efficiency compared to higher-channel-count counterparts.
