PM4328 TECT3
HIGH DENSITY T1/E1 FRAMER
AND M13 MULTIPLEXER
· 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.
· Provides robbed bit signaling extraction and insertion on a per-DS0 basis.
· Provides programmable idle code substitution, data and sign inversion, and
digital milliwatt code insertion on a per-DS0 basis.
· Supports the M23 and C-bit parity DS3 formats.
· Standalone unchannelized DS3 framer mode for access to the entire DS3
payload.
· 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.
· DS3 Transmit clock source can be selected from either an external oscillator
or from the receive side clock (loop-timed).
· 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.
· Provides a generic 8-bit microprocessor bus interface for configuration,
control and status monitoring.
· Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board
test purposes.
· Low power 2.5V/3.3V CMOS technology. All pins are 5V tolerant.
· 324-pin fine pitch PBGA package (23mm x 23mm). Supports industrial
temperature range (-40oC to 85oC) operation.
Each one of 28 T1 receiver sections:
· Frames to DS-1 signals in SF and ESF formats.
· Frames to TTC JT-G.704 multiframe formatted J1 signals. Supports the
alternate CRC-6 calculation for Japanese applications.
· Accepts gapped data streams to support higher rate demultiplexing.
