FEATURES
Rate buffer for T1 and CEPT transmission
systems
Synchronizes loop–timed and system timed
data streams on frame boundaries
Ideal for T1 (1.544 MHz) to CEPT (2.048
MHz), CEPT to T1 interfaces
Supports parallel and serial backplanes
Buffer depth is 2 frames
Comprehensive on–chip “slip” control logic
– Slips occur only on frame boundaries
– Outputs report slip occurrences and
direction
– Align feature allows buffer to be recentered
at any time
– Buffer depth easily monitored
Compatible with DS2180A T1 and DS2181A
CEPT Transceivers
Industrial temperature range of –40
°
C to
+85
°
C available, designated DS2175N

DESCRIPTION
The DS2175 is a low–power CMOS elastic–store memory optimized for use in primary rate telecommu-
nications transmission equipment. The device serves as a synchronizing element between async data
streams and is compatible with North American (T1–1.544 MHz) and European (CEPT–2.048 MHz) rate
networks. The chip has several flexible operating modes which eliminate support logic and hardware cur-
rently required to interconnect parallel or serial TDM backplanes. Application areas include digital
trunks, drop and insert equipment, digital cross–connects (DACS), private network equipment and
PABX–to–computer interfaces such as DMI and CPI.
