Microsemi's multichannel 10 GbE transceivers capture the highest port
density at the lowest cost.
Microsemi’s dual channel and quad channel XAUI-to-serial transceivers,
VSC8488 and VSC8484, deliver minimum cost per channel with
maximum port densities at the lowest power. The devices achieve
an excellent 1 W per channel power dissipation while supporting the
increased port densities required for next-generation 10 Gbps platforms.
The VSC8488 and VSC8484 integrate Microsemi's world-class
electronic dispersion compensation (EDC) performance across multiple
data rates: 9.95 Gbps WAN, 10.3 Gbps Ethernet (GbE), and 10.5Gbps
Fibre Channel. The devices also meet the SFP+ SR/LR/LRM host
requirements in accordance with the SFF-8431 and IEEE 802.3aq
specifi cations.
The EDC capabilities are optimized by the VScope™ input signal
monitoring integrated circuit, which delivers more accurate, in-line views
of the post-equalization waveform.
The VSC8488 and VSC8484 compensate for optical impairments
in SFP+ LRM applications, along with degradations of the PCB,
while providing wide system margin for SR and LR applications. The
transmit path incorporates a multi-tap output driver to provide the
fl exibility required to meet the demanding 10GBASE-KR (IEEE 802.3ap)
standard.
A complete suite of BIST functionality includes line and client loopbacks
along with pattern generation and error detection. Highly fl exible
clocking options support either LAN or WAN operation, along with
seamless Synchronous Ethernet. Both devices include selectable
lane ordering; the VSC8484 includes failover switching capability for
protection routing.
The VSC8488 device supports three serial interface confi gurations:
MDIO, two-wire serial slave, and two-wire serial master. This highly
fl exible communication scheme, along with a minimum of 12
programmable GPIO pins, allows for independent control of the
VSC8488 and VSC8484 channels while providing access to a wide
range of device monitors and XFP/SFP+ module management.
