HIGH DENSITY T1/E1 FRAMER
AND M13 MULTIPLEXER
Sꢀ Also provides PRBS generators and detectors on each tributary for error
testing at DS1, E1 and NxDS0 rates as recommended in ITU-T O.151 and
O.152.
Sꢀ Provides robbed bit signaling extraction and insertion on a per-DS0 basis.
Sꢀ Provides programmable idle code substitution, data and sign inversion, and
digital milliwatt code insertion on a per-DS0 basis.
Sꢀ Supports the M23 and C-bit parity DS3 formats.
Sꢀ Standalone unchannelized DS3 framer mode for access to the entire DS3
payload.
Sꢀ When configured to operate as a DS3 Framer, gapped transmit and receive
clocks can be optionally generated for interface to link layer devices which
only need access to payload data bits.
Sꢀ DS3 Transmit clock source can be selected from either an external oscillator
or from the receive side clock (loop-timed).
Sꢀ Register level compatibility with the PM4388 TOCTL Octal T1 Framer, the
PM6388 EOCTL Octal E1 Framer, the PM4351 COMET E1/T1 transceiver
and the PM8313 D3MX M13 Multiplexer/Demultiplexer.
Sꢀ Provides a generic 8-bit microprocessor bus interface for configuration,
control and status monitoring.
Sꢀ Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board
test purposes.
Sꢀ Low power 2.5V/3.3V CMOS technology. All pins are 5V tolerant.
Sꢀ 324-pin fine pitch PBGA package (23mm x 23mm). Supports industrial
temperature range (-40oC to 85oC) operation.
Each one of 28 T1 receiver sections:
Sꢀ Frames to DS-1 signals in SF and ESF formats.
Sꢀ Frames to TTC JT-G.704 multiframe formatted J1 signals. Supports the
alternate CRC-6 calculation for Japanese applications.
Sꢀ Accepts gapped data streams to support higher rate demultiplexing.
