VSC7227YKV-01 Interface - Specialized 12 Channel Multirate 11.5 Gbps Retimer

Description

The VSC7227 devices are 12-channel unidirectional adaptive channel extenders with CDR. They

incorporate analog and digital equalization, clock and data recovery, and output de-emphasis.

VSC7227-02 supports data rates up to 15.5G. VSC7227 supports data rates up to 14.5G, and

VSC7227-01 supports data rates up to 11.5G. The devices are ideal for applications such as

Ethernet, Fibre Channel, Infiniband, and Common Public Radio Interface (CPRI), as well as other protocols.

The VSC7227 devices are simple-to-use copper media receivers and drivers that provide electrical

compensation to cable, copper, and backplane environments to increase system margin and media

driving distances. They equalize greater than 40 inches of FR-4 at 10G and greater than 10 m of 24AWG

of copper direct-attached cable at 10G. The VSC7227 devices can be used either on their own or with an

external microcontroller to control, monitor, and enhance system performance.

The VSC7227 devices feature Microchip's proprietary FlexEQ™ technology to equalize deteriorated input

signals while dissipating the lowest possible power. A low-cost 25 MHz crystal, along with on-chip frequency

synthesizers, allows for CDR operation at any data rate. Its three-tap FIR output driver architecture enables

up to 18 dB of de-emphasis. The VSC7227 devices include Microchip's patented VScope input signal

monitoring integrated circuit signal monitoring and waveform viewing technology.
