SY88808L Datasheet, PDF (1/10 Pages) Micrel Semiconductor – 10.3Gbps Transceiver with Programmable Equalization

SY88808L
10.3Gbps Transceiver with
Programmable Equalization
General Description
The SY88808L high-speed transceiver is optimized for
active copper cable assembly, backplane, and
transmission line data-path management applications. The
SY88808L is capable of equalizing serial data up to
10.3Gbps across up to 36 inches of FR4 or 10 meters of
26 AWG cable.
The SY88808L differential inputs can directly interface to
any differential signal as small as 150mV_PK. Both channels
of the transceiver have programmable EQ on the receiving
end. The output of the transmitter can be programmed to
provide an output swing from 100mV_PK to 350mV_PK. The
output is optimized to drive into a 50Ω load.
The AnyLength equalization circuit in the receiver can be
programmed to optimize the eye of the data signal
received from 0” to 36” of FR4 or 0m to 10m of 26AWG
cable. Unlike discrete EQ settings, patent-pending
AnyLength EQ provides optimal results as well as saves
power.
The SY88808L operates at 3.3V ±5% supply and its
operation is guaranteed over the commercial temperature
range of 0°C to +70°C. The SY88808L is part of Micrel’s
high-speed, Precision Edge^® product line.
