| Extended PCM Interface Controller - Small (EPIC(R)-S) PEB 2054 General Description Information from subscriber lines needs to be transferred to time-slots on system internal PCM communication highways. The EPIC-S concentrates the circuitry necessary to do this interfacing for a large number of transmission lines on a single IC. Therefore, it is not necessary to repeat this PCM interface circuitry for every line. Applications of the EPIC-S include communications multiplexers, concentrators, central switches, PBXs, as well as peripheral ISDN and analog line cards. Features * PCM interface controller for up to 16 ISDN or 32 analog subscribers * Time-slot assignment freely programmable for all subscribers * Non-blocking switch for 64 channels * Switching of 16-, 32-, 64-kbit/s channels (128 kbit/s via two consecutive 64-kbit/s channels) Type PEB 2054-N PEF 2054-N Package P-LCC-44-1 (SMD) P-LCC-44-1 (SMD) * Two serial interfaces: PCM and configurable * Programmable for a wide range of data rates (PCM up to 8 Mbit/s, configurable up to 4 Mbit/s) * Data rates of PCM and configurable interfaces independent of each other (data rate adaption) * Change detection ("last look") logic for C/l or signaling channels * 16-byte FIFO for monitor or feature control channels * Standard P interface with multiplexed address/data bus or separate address and data busses * Advanced low power CMOS technology * Also available with extended temperature range - 40 to 85 C (PEF 2054-N) * Pin compatible with PEB 2055 RES DCL FSC Timing PDC PFS DD0 DU0 Configurable Interface DD1 DU1 Data Memory PCM Interface RxD 0 TxD 0 TSC 0 RxD 1 TxD 1 TSC 1 RxD 2 TxD 2 TSC 2 RxD 3 TxD 3 TSC 3 Control Memory Layer-1 Controller Buffer P Interface Block Diagram AD0-AD7 WR RD CS ALE INT 1 ITB05888 Siemens Aktiengesellschaft |
