VSC7223
Multirate 16 Gbps Quad Adaptive Channel Extender with All-Rate CRU
Microsemi’s advanced unidirectional lane adaptive channel extender
equalizes deteriorated input signals while dissipating the lowest possible
power.
The VSC7223 device is a quad unidirectional lane adaptive channel
extender with a CRU. It incorporates input equalization, clock and data
recovery, and output de-emphasis. It operates at data rates from 155
Mbps to 16 Gbps.
The VSC7223 device is a simple-to-use copper media receiver and
driver that provides electrical compensation to cable, copper, and
backplane environments to increase system margin and media driving
distances. It equalizes greater than 65 inches of FR-4 at 10 Gbps and
greater than 15 meters of 24AWG of SFP+ copper direct-attached cable
at 10 Gbps.
The VSC7223 device can be used either on its own or with an external
microcontroller to control, monitor, and enhance system performance.
The VSC7223 device uses advanced technology to equalize
deteriorated input signals while dissipating the lowest possible power. A
low-cost 25 MHz crystal, along with an on-chip frequency synthesizer,
allows for CRU operation at any data rate. Its three-tap FIR output driver
architecture enables up to 20 dB of de-emphasis at 10 Gbps.
The VSC7223 device includes Microsemi’s patented VScope™ input
signal monitoring integrated circuit waveform viewing technology.
The VSC7223 device is available in a compact 5 mm x 9 mm 48-pin
QFN package. The device operates on a single supply of 1.2 volts.
