1 / 8 page Order this document from Logic Marketing MOTOROLA SEMICONDUCTOR TECHNICAL DATA © Motorola, Inc. 1994 4/94 REV 0 Advance Information CMI Coder/Decoder The MC100SX1230 device consists of a Binary to CMI Coder and CMI to Binary Decoder with integrated loop back capability. The device is designed for CMI (Code Mark Inversion) interfaces in transmission applications supporting either 139.26 Mbit/s E4 or 155.52 Mbit/s STM1 line rates. • Binary-to-CMI Coder and CMI-to-Binary Decoder • Internal Loop Back Test Capability • Supports SDH or PDH Applications • Low Power • Fully Differential 100K Compatible I/O • VBB Reference Available • 75kΩ Input Pulldown Resistors • +5V PECL or –5V ECL Operation • 28-Pin Surface Mount PLCC Package • Asynchronous Reset In normal operation, the coder and decoder operate independently. Both the coder and decoder operate from a 2X line rate clock. The device incorporates test circuitry to support loop back bypass so either the coder input can be routed to the decoder output or the decoder input can be routed to the coder output. The part is fabricated using Motorola’s proven MOSAIC III ™ advanced bipolar process. The device provides a VBB output for accepting single-ended inputs. The VBB pin should only be used as a bias for the MC100SX1230 as its current sink/source capability is limited. Whenever used, the VBB pin should be bypassed to ground via a 0.01 µF capacitor. 1 DCLKout VCC VCC VCCO VCCO N/C N/C RESET VBB DCLKin DCLKin VEE VEE LBIN LCMI 4 3 2 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 7 8 6 5 Pinout: 28-Lead PLCC (Top View) CMIin CCLKout CMIin QCMI BINin QCMI BINin QBIN CCLKin QBIN CCLKin DCLKout CCLKout MOSAIC III is a trademark of Motorola, Inc.
