XRT71D00
E3/DS3/STS-1 JITTER ATTENUATOR
SEPTEMBER 2001
REV. 1.2.0
GENERAL DESCRIPTION
The XRT71D00 is a single channel, single chip Jitter
Attenuator, that meets the Jitter transfer characteristic
requirements specified in the ETSI TBR-24, Bellcore
GR-499-CORE and GR-253-CORE standards.
In addition, the XRT71D00 also meets the Output Jit-
ter and Wander specifications described in the ANSI
T1.105.03b 1997, Bellcore GR-253-CORE and GR-
499-CORE standards.
FEATURES
Meets E3/DS3/STS-1 jitter transfer requirements
No external components required
Compliant with the jitter transfer characteristic
requirements specified in ITU G.751, G.752, and
G.755 for E3 applications
Meets jitter transfer characteristic requirement as
specified by ETSI TBR24 (for E3 applications).
Meets the Output Jitter and Wander specifications
described in ANSI T1.105.03b, Bellcore GR-253-
CORE and Bellcore GR-499-CORE standards.
Selectable buffer size of 16 and 32 bits
Jitter attenuator can be disabled
Available in a 32 pin TQFP package.
Single 3.3V or 5.0V supply.
Operates over - 400 C to 850 C temperature range.
APPLICATIONS
E3/DS3 Access Equipment.
