| PRODUCT BRIEF Advanced Communications ACS406CS 4 x E1/T1 Fiber Mux 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 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. * Multi-channel operation with full loopback diagnostics * Up to 8 independent synchronous data channels: 1 x E2/T2 4 x E1/T1 transmission up to 8.448Mbps over one fiber per channel * 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 85C * ACS9010 available in TQFP44 package, ACS4060 available in TQFP100 package. xto xti 8 x 1.024Mbps BLOCK DIAGRAM rclk1 rpos1 rneg1 LINE CODER P2S PLL ACS4060 XTAL OSC 4x rclk4 rpos4 rneg4 rmclk rmd1 tclk1 tpos1 tneg1 tclk4 tpos4 tneg4 tmclk tmd1 S2P MODE CONTROL / STATUS LINE DEC S2P LINE DEC S2P TX CONTROL PING PONG ENGINE P2S LINE CODER P2S PLL RX FIFO 8B10B DEC PLL RX AND LOCK CONTROL PING PONG ENGINE LED/Laser Driver PIN Receiver S2P REC PLL DATA SLICE ACS9010 4x TX FIFO 8B10B CODER P2S errc errl dcd loss Semtech reserves the right to change specifications on catalog devices without notice.
