PRODUCT BRIEF ACS406CS 4 x E1/T1 Fiber Mux Advanced Communications 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.
