Description

The DS2176 is a low-power CMOS device specifically designed for synchronizing receive-side loop-timed T-carrier data streams with system-side timing. The device has several flexible operating modes that simplify interfacing incoming data to parallel and serial TDM backplanes. The device extracts, buffers and integrates ABCD signaling; signaling updates are prohibited during alarm or slip conditions. The buffer replaces extensive hardware in existing applications with one "skinny" 24-pin package. Application areas include digital trunks, drop and insert equipment, transcoders, digital cross-connects (DAC), private network equipment, and PABX-to-computer interfaces such as DMI and CPI.

Key Features

Synchronizes loop-timed and system-timed T1 data streams Two-frame buffer depth; slips occur on frame boundaries Output indicates when slip occurs Buffer can be recentered externally Ideal for 1.544 to 2.048MHz rate conversion Interfaces to parallel or serial backplanes Extracts and buffers robbed-bit signaling Inhibits signaling updates during alarm or slip conditions Integration feature "debounces" signaling Slip-compensated output indicates when signaling updates occur Compatible with DS2180A T1 transceiver Surface mount package available, designated DS2176Q Industrial temperature range of -40°C to +85°C available, designated DS2176N
