| PM4354 COMET-QUAD Four Channel Combined E1/T1/J1 Transceiver/Framer FEATURES * Monolithic device that integrates four T1/E1 framers and line interfaces for shorthaul and longhaul applications. * Software selectable between T1/J1 and E1 operation on a per device basis. * Provides digitally programmable longhaul and shorthaul pulse templates and line build out. * Meets or exceeds T1/J1 and E1 shorthaul and longhaul network access specifications including ANSI T1.102, T1.403, T1.408, AT&T TR 62411, ITUT G.703, G.704 as well as ETSI 300011, CTR-4, CTR-12 and CTR-13. * Provides encoding and decoding of B8ZS, HDB3 and AMI line codes. * Provides receive equalization, clock recovery and line performance monitoring. * Provides transmit and receive jitter attenuation. * Provides four full-featured HDLC controllers, each with 128-byte transmit and receive FIFO buffers. * Provides a two-frame payload slip buffer to allow independent backplane and line timing. * Automatically generates and transmits DS-1 performance report messages to ANSI T1.231 and ANSI T1.408 specifications. * Provides PRBS generators and detectors on each tributary for error testing at DS1, E1 and N x 64 Kbit/s rates as recommended in ITU-T O.151 and O.152. * Provides an 8-bit microprocessor bus interface for configuration, control, and status monitoring. * Uses line rate system clock. * Provides an IEEE P1149.1 (JTAG) compliant test access port (TAP) and controller for boundary scan test. * Implemented in a low power 2.5/3.3 V CMOS technology. * Available in a high density 208-pin fine pitch PBGA (17 mm by 17 mm) package. * Provides a -40 C to +85 C industrial temperature operating range. RECEIVER * Typical signal recovery of up to -43 dB at 1024 kHz (E1) and up to -44 dB at 772 kHz (T1/J1). * Guaranteed minimum signal recovery of -32 dB at 1024 kHz (E1) and -36 dB at 772 kHz (T1/J1) using PIC-22 gauge cable emulation. * Frames to DSX/DS-1 signals in SF, and ESF formats. * Frames to ITU-T G.704 basic and CRC-4 multiframe formatted E1 signals. The framing procedures are consistent with ITU-T G.706 specifications. * Frames to TTC JT-G704 multiframe formatted J1 signals. Supports the alternate CRC-6 calculation for Japanese applications. Frames in the presence of and detects the Japanese yellow alarm. * Tolerates more than 0.4 UI peak-topeak, high frequency jitter as required by AT&T TR 62411 and Bellcore TRTSY-000170. * Provides programmable in-band loopback activate and deactivate code detection.
