9.953 to 10.709 Gb/s / 11.3 Gb/s SONET/SDH/10GE Transceiver with Integrated
Clock Generator and Clock Recovery
VSC8473
The VSC8473 is a 1:16 16:1 transceiver with
integrated Clock and Data Recovery unit
(CDR) and Clock Multiplier Unit (CMU), and
provides the most comprehensive solution
available for 300 pin module and DWDM
line card applications, with industry leading
optimization of power, performance, price and feature integration.
The 1.15 W total power dissipation enables module vendors to
provide performance and functionality advantages while dropping the
overall power dissipation of their existing modules. Full temperature
range and supply operation spans from 9.953 Gb/s to 10.709 Gb/s for
the VSC8473, and up to 11.3 Gb/s for the VSC8473-01. This provides
the most complete coverage in the industry of all operating rates
including SONET/SDH (9.95 Gb/s), 10GE (10.3 Gb/s), 10G Fibre
Channel (10.5 Gb/s), G.709 (10.7 Gb/s), 10GE+FEC (11.1 Gb/s) and
10G Fibre Channel + FEC (11.3 Gb/s.) The VSC8473 also provides an
excellent host SERDES capability for XFP module applications.
It fully supports all features, functions and clock modes required for
300-pin multi-source agreement (MSA) transponder module full
compliance. All loopback modes are supported with multiple line
timing clock modes. A highly flexible reference clock source selection
G E N E R A L D E S C R I P T I O N :
and reference clock clean-up support scheme is provided to minimize
external circuitry. An I
2
C serial interface provides full micro-controller
access to all status and control registers. Any combination of
discrete pins and serial register status and control can be employed.
Robust crosstalk immunity enables the VSC8473 to operate the Tx
and Rx paths asynchronously to each other while exceeding SONET
level jitter generation and jitter tolerance performance. A high-
speed output clock can be optionally enabled for higher
performance applications. An adjustable loss of signal (LOS)
indicator is integrated into the device enabling optical modulation
amplitude monitoring.
The power supply scheme provides a high degree of flexibility. It can
operate on a single +1.8V supply with an optional +3.3V I/O supply
for interfacing. The single chip, small footprint (17 x 17 mm) design
allows for both cost reduction and board size reduction for price-
and-size aggressive, small form factor module applications. A pin-
compatible VSC8477 device provides additional functions including
full data eye phase and threshold adjust, sample optimization and
data eye mapping capabilities. All VSC8473/77 devices are tested
at high-speed to ensure the highest performance and quality
standards you've come to expect from Vitesse.
