PM6341-RI
E1 FRAMER/TRANSCEIVER
FEATURES
• Monolithic single chip device which
integrates a full-featured E1 framer
with on-chip analog line interface.
• Provides frame synchronization and
frame generation for a G.704/G.706
2.048 Mbit/s signal with capability to
support the optional signalling and
CRC multiframes.
• Supports HDB3 or AMI line coding
and accepts gapped data streams to
support higher rate demultiplexing.
• Supports both 75 Ohm and 120 Ohm
G.703 line interfaces.
• Provides Channel Associated
Signalling extraction/insertion,
programmable idle code substitution,
digital milliwatt code substitution,
data inversion and up to 3
multiframes of signalling debounce
on a per channel basis.
• Optionally extracts/inserts the
datalink from/to timeslot 16 to
receive/transmit Common Channel
Signalling.
• Pin compatible with the PM4341A
T1XC T1 Transceiver.
• Software compatible with the
PM6344 EQUAD E1 Framer, and
PM6388 EOCTL E1 Framer.
• Provides an 8-bit microprocessor bus
interface for configuration, control
and status monitoring.
• Low-power 5V CMOS technology.
• Available in a high density 80-pin (14
by 14mm) PQFP or in a 68-pin PLCC
package
