DESCRIPTION
The ACS406CS comprises a chip set of two highly
integrated devices, the ACS9010 and ACS4060. The
ACS9010 is an analog transceiver device and the
ACS4060 is a mixed signal device.
The ACS406CS supports full duplex serial data of up to
8.448Mbps over one fiber with link lengths up to 25km.
The available bandwidth can be shared over 1 to 8
channels of 1 x E2/T2, 4 x E1/T1, 8 x 1.024Mbps plus
separate maintenance channel(s). The ACS406CS
provides five transmit/receive clock domains enabling
four independent E1/T1 channels and a maintenance
channel to be supported at one time.
The ACS9010 is a transceiver which integrates the Laser/
LED driver as well as the PIN receiver circuitry including
the TIA and post amplifier.
The ACS4060 integrates the multi-channel mux/de-mux
logic with de-jittering circuits for each channel, plus the
clock and data recovery. Communicating modems
automatically maintain synchronisation with each other
even when no data is being transmitted/received. Link
lengths from zero to maximum distance are catered for
automatically during system synchronisation.
