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.
