XRT71D03
3 CHANNEL E3/DS3/STS-1 JITTER ATTENUATOR, STS-1 TO DS3 DESYNCHRONIZER
DECEMBER 2000
REV. P1.0.2
GENERAL DESCRIPTION
The XRT71D03 is a three channel, single chip Jitter
Attenuator, that meets the Jitter transfer characteris-
tics requirements specified in the ETSI TBR-24,
Bellcore GR-499 and GR-253 standards.
In addition, the XRT71D03 also meets the Jitter and
Wander specifications described in the ANSI
T1.105.03b 1997, Bellcore GR-253 and GR-499 stan-
dards for Desynchronizing and Pointer adjustments in
the DS3 to STS-SPE mapping applications.
FEATURES
Meets the E3/DS3/STS-1 jitter requirements
No external components required
Compliant with jitter transfer template outlined in
ITU G.751, G.752, G.755, GR-235-CORE, GR-
499-CORE,1995 standards
Meets output jitter requirement as specified by
ETSI TBR24
Meets the Jitter and Wander specifications
described in T1.105.03b,GR-253 and GR-499 stan-
dards.
Selectable buffer size of 16 and 32 bits
Jitter attenuator can be disabled
Available in a 64 pin LQFP package.
