The 40 Gbit/s transceiver chipset (MUX+FIFO and CDR+DEMUX)
provide highly integrated SerDes (SERializer-DESerializer) func-
tionality with a 1:16 ratio. The 16 times 2.5 Gbit/s data signals
are multiplexed to a single serial 40 Gbit/s data stream and vice
versa. The devices support datarates from 39.8 Gbit/s up to
43 Gbit/s (OC-768/STM-256) with optional FEC (Forward Error
Correction). All four chips are manufactured in Infineon's
leading-edge Silicon-Germanium B7HF technology enabling low
power consumption.
The multiplexer FOA4400, FIFO FOA9400, demultiplexer FOA5400
and CDR FOA5401 feature CML interfaces, integrated VCOs
(Voltage-Controlled Oscillator) and two reference clocks
(622 MHz/2.5 GHz). The FOA4400 incorporates the CMU and
selectable 20 GHz and 40 GHz clock outputs, whereas optional
data synchronization is provided by the FOA9400. The FOA5400
and FOA5401 integrate CDR and demultiplexing functionality
with extremely high input sensitivity.
