Data Sheet

Quad 10/100/1000BASE-T PHY with RGMII and RTBI MAC Interfaces

1 General Description

Ideally suited for high port density Gigabit Ethernet switches

and routers, or multi-port Network Interface Cards (NICs),

Vitesse'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).

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.

To enable maximum network management feedback to the

host system and the user, the VeriPHY^®Link Management

and Cable Diagnostics Suite can be used with the device.

VeriPHY provides extensive network and cable plant

operating and status information, such as the cable length,

termination status, and open/short fault location. VeriPHY

integrates with NIC or switch software to greatly simplify

Gigabit Ethernet network deployment and management by

providing the functionality equivalent to a hand-held cable

tester.

The VSC8244 physical layer "PHY" IC leverages Vitesse’s

proprietary 4th generation DSP Technology. Vitesse'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
