Revision 1.3 March 2000
4 x E1/T1 Fiber Mux/De-mux over One Fiber Optic Cable
FEATURES
DESCRIPTION
The ACS406CS comprises a chip set of two highly · Two chip set supporting full duplex serial data
transmission up to 8.448Mbps over one fiber
integrated devices, the ACS9010 and ACS4060. The
ACS9010 is an analog transceiver device and the
ACS4060 is a mixed signal device.
· Multi-channel operation with full loopback diagnostics
per channel
· Up to 8 independent synchronous data channels:
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.
1 x E2/T2
4 x E1/T1
8 x 1.024Mbps
· Additional 64kbps maintenance channel with option of
4 x 16kbps multi-channel operation and framing signal
for main channels
· Standard interfaces for Line Interface Units (LIU) or
Framers
· Select between NRZ and pseudo-bipolar HDB3/AMI/
B8ZS input data coding types
· Support for Bi-Directional, single wavelength
duplexers and LED/Laser + PIN
· Link lengths up to 25km on single mode fiber
· Typical latency of 0.75ms
· 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.
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.
