1 General Description
Ideally suited for high port density Gigabit Ethernet switches
and routers, or multi-port Network Interface Cards (NICs),
Microsemi's VSC8244 integrates four low-power, triple speed
(10BASE-T, 100BASE-TX, and 1000BASE-T) Ethernet
transceivers in thermally-enhanced, 260-pin plastic Ball Grid
Array (BGA).
The VSC8244 physical layer "PHY" IC leverages Microsemi’s
proprietary 4th generation DSP Technology. Microsemi's
highly optimized DSP architecture yields industry leading
performance at less than 640mW per port, supporting
1000BASE-T with respect to all worst case impairments
(NEXT, FEXT, Echo, and system noise sources).
Each of the four independent triple-speed transceivers
features pin-efficient RGMII and RTBI compliant MAC
interfaces. On-chip RGMII/RTBI series termination resistors
simplify board design challenges by improving signal integrity
and completely eliminating dozens of external series
termination resistors on the receive side of the MAC
interface. In addition, the VSC8244 integrates, for the first
time in the industry, all copper media side line termination
resistors.
The VeriPHY® suite has the ability to identify the cable length
and operating conditions and to isolate common faults that
can occur on Cat5 twisted pair cabling.
