Product Description
The CS4223 EDC PHY is a serial 15 Gbps Quad PHY with 8 Port CDR
Electronic Dispersion Compensation (EDC). The device's 28 nm
architecture enables higher port counts and increased faceplate and
backplane bandwidth for next generation data center, carrier, and
enterprise systems. The CS4223 EDC PHY leads the industry with less
than 1 ns latency in a 12 mm × 12 mm package, while lowering power
consumption by 50% over previous generations. The CS4223 EDC PHY
provides a wide operating frequency range covering 1 GbE, 10 GbE,
1G FC, 2G FC, 4G FC, 8G FC, 16G FC, Infiniband SDR, DDR, QDR, FDR,
CPRI Options 1 to 7, and support for all the major standards used in
data centers, storage, high performance computing, and wireless
backhaul applications including 1 GbE, 10 GbE, 40 GbE, 100 GbE,
InfiniBand, Fibre Channel, CPRI, and OBSAI.
The CS4223 EDC PHY functionality supports four full-duplex 10G links,
or one full-duplex 40G link. EDC capability allows the device to operate
with linear SFP+/QSFP optical modules, Direct Attach Copper,
40GBase-CR4 cables, and 10GBase-ZR and DWDM SMF applications.
The device is fully compliant to 10G SFP+, 802.3ba 40G and 100G
nPPI, and nAUI specifications. The fully autonomous device does not
require external processors to control the convergence or dynamic
adaption of the dispersion compensation. The CS4223 EDC PHY also
integrates the auto negotiation and coefficient training functionality for
40G KR4/CR4 applications, and rate negotiation 16G Fibre channel, for
seamless interoperability with existing equipment.
The CS4223 EDC PHY includes an integrated 2 × 2 switch enabling
redundant backplane and faceplate applications without needing an
external crossbar device. The integrated switch functionality supports
1+1 protection switching and broadcast functionality in both
directions. The device supports link quality monitoring for the inactive
redundant link to enable fast switching. In addition, the
CS4223 EDC PHY has a fully symmetric architecture with EDC
capability on both ingress and egress directions. This enables
applications such as translation from KR4 backplane to CR4 cable in
blade server designs using a single device, reducing system cost.
The CS4223 EDC PHY has integrated AC coupling capacitors on all
receiver inputs to reduce overall system BOM cost. The device also
includes capabilities such as real time eye monitoring, loopbacks,
PRBS generators and checkers, hardware interrupt, and GPIO pins for
test and debug purposes.
