DP83850C 100 Mb/s TX/T4 Repeater Interface Controller
(100RIC™
)
General DescriptionThe DP83850C 100 Mb/s TX/T4 Repeater Interface Con-
troller, known as 100RIC, is designed specifically to meet
the needs of today's high speed Ethernet networking sys-
tems. The DP83850C is fully compatible with the IEEE
802.3 repeater's clause 27.
The DP83850C supports up to twelve 100 Mb/s links with
its network interface ports. The 100RIC can be configured
to be used with either 100BASE-TX or 100BASE-T4 PHY
technologies. Larger repeaters with up to 372 ports may
be constructed by cascading DP83850Cs together using
the built-in Inter Repeater bus.
In conjunction with a DP83856 100 Mb/s Repeater Infor-
mation Base device, a DP83850C based repeater
becomes a managed entity that is compatible with IEEE
802.3u (clause 30), collecting and providing an easy inter-
face to all the required network statistics.

Features IEEE 802.3u repeater and management compatible Supports Class II TX translational repeater and Class I
T4 repeater Supports 12 network connections (ports) Up to 31 repeater chips cascadable for larger hub appli-
cations (up to 372 ports) Separate jabber and partition state machines for each
port Management interface to DP83856 allows all repeater
MIBs to be maintained Large per-port management counters - reduces man-
agement CPU overhead On-chip elasticity buffer for PHY signal re-timing to the
DP83850C clock source Serial register interface - reduces cost Physical layer device control/status access available via
the serial register interface Detects repeater identification errors 132 pin PQFP package
