Overview of PM4354-NGI
Key Features
- Monolithic device which integrates four, full-featured T1 and E1 framers and T1 and E1 short haul and long haul line interfaces.
- Software selectable between T1/J1 and E1 operation on a per-device basis.
- Meets or exceeds T1 and E1 shorthaul and longhaul network access specifications including ANSI T1.102, T1.403, T1.408, AT&T TR 62411, ITU-T G.703, G.704 as well as ETSI 300-011, 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 digitally programmable long haul and short haul line build out.
- Provides four full-featured HDLC controllers, each with 128-byte transmit and receive FIFO buffers.
- Automatically generates and transmits DS-1 performance report messages to ANSI T1.231 and ANSI T1.408 specifications.
- Supports Nx64Kbit/s fractional bandwidth backplane.
- Supports transfer of PCM data to/from 1.544MHz and 2.048MHz system-side devices. Also supports a fractional T1 or E1 system interface with independent backplane receive/backplane transmit Nx64Kbit/s rates. Supports a 2.048 MHz system-side interface for T1 mode without external clock gapping.
- Supports 8.192 Mbit/s, H-100 compatible, H-MVIP on the system interface for all T1 or E1 links, a separate 8.192 Mbit/s H-MVIP system interface for all T1 or E1 CAS channels and a separate 8.192 Mbit/s H-MVIP system interface for all T1 or E1 CCS, V5.1/V5.2, and GR.303 channels.
- Provides a selectable, per channel independent de-jittered T1 or E1 recovered clock for system timing and redundancy.
- Provides PRBS generators and detectors on each tributary for error testing at DS1, E1 and Nx64Kbit/s rates as recommended in ITU-T O.151 and O.152.
- Provides robbed bit signaling extraction and insertion on a per-DS0 basis.
- Register level compatibility with the PM4388 TOCTL Octal T1 Framer, the PM6388 EOCTL Octal E1 Framer, the PM4351 COMET E1/T1 transceiver, and the PM8315 TEMUX T1/E1 Framer with integrated Mapper and M13 MUX.
- 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 5 V tolerant 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.
