ACS406CS
4 x E1/T1 Fiber Mux
Revision 1.3 March 2000
Advanced Communications
4 x E1/T1 Fiber Mux/De-mux over One Fiber Optic Cable
DESCRIPTION
FEATURES
The ACS406CS comprises a chip set of two highly ·Two chip set supporting full duplex serial data
ACS9010 is an analog transceiver device and the ·tMraunltsi-mchisasnionneluoppteora8t.i4o4n8wMitbhpfsulol vloeorpobnaeckfibdeiargnostics
integrated devices, the ACS9010 and ACS4060. The
·Upeprtcoh8aninndeelpendent synchronous data channels:
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.

·Typical latency of 0.75ms
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.
·Bit Error Rate (BER) of 10-10
·Low power, single 5V supply
·Operating temperature (ambient) of -40 to 85°C
·ACS9010 available in TQFP44 package, ACS4060
available in TQFP100 package.
