PM7344,pdf datasheet (Quad T1/

FEATURES
? Monolithic single-chip quad ATM
Physical Layer User Network Interface
(UNI) operating at 1.544 Mbit/s or
2.048 Mbit/s.
? Integrates a quad full-featured dualmode
T1/E1 framer/transmitter for
terminating four duplex 1.544 Mbit/s
DS1 or four duplex 2.048 Mbit/s E1
signals. Recovers T1/E1 clock and
data using a digital phase locked loop
for high jitter tolerance.
? Implements the ATM Forum UNI
Specification V3.1 for DS1 and E1
transmission rates.
? Implements the ATM physical layer for
Broadband ISDN according to ITU-T
Recommendation I.432.
? Implements direct mapping into four T1
or E1 streams according to ITU-T
Recommendation G.804.
? Provides UTOPIA L1-compliant,
UTOPIA L2-compatible ATM-PHY
interface with parity and multi-PHY
control signals.
? Software-compatible with the
PM4341A T1XC, PM6341 E1XC,
PM4351 COMET, PM5346 S/UNI?-
LITE and PM7345 S/UNI-PDH.
? Application-compatible with the
PM8313 D3MX, PM4314 QDSX, and
PM7323 RCMP-200.
? Provides a generic 8-bit
