TM-056

Integrated Timing Solution

The TM-056 is a compact Timing Module, which functions as a complete system clock solution for general Stratum 3/3E timing applications. The

gen

TM-056 uses Vectron’s Digital and Analog Phase Locked Loop (DPLL and APLL) technology and can lock to 2 re

cked

reference frequencies automatically.

Features

• Single module Statum 3/3E synchronization solution.

• Complies with Telcordia GR-1244/GR-253 and ITU-T G.812/G.813

recommendations.

• Supports Free-run, Holdover and Lock modes.

• Accepts 2 reference inputs from frequency range 8kHz to 77.76MHz.

• Continuously monitors and evaluates both input reference signals

simultaneously.

• Provides two synchronized outputs with frequency range up to 77.76MHz.

• On board OCXO that provides excellent stability in Freerun and Holdover

mode.

• Loop ﬁltering utilizing DPLL.

• Automatic “hit-less” switchover on loss of input.

• Holdover mode with 90 seconds of history.

• Several alarms and status signals.

• Simple control interface and JTAG port for factory programming.

• Small dimensions 1.9” x 1.9” x 0.55”

• Product is compliant to RoHS directive and fully compatible with lead free

assembly.
