DS3100 Datasheet Stratum 2/3e/3 Timing Card-ic

Manufacturer: Microsemi (now Microchip Technology)

Overview: Data Sheet April 2019 DS3100 Stratum 2/3E/3 Timing Card IC General.

General Description

When paired with an external TCXO or OCXO, the DS3100 is a plete central timing and synchronization solution for SONET/SDH network elements.

With two multiprotocol BITS/SSU receivers and 14 input clocks, the device directly accepts both external timing and line timing from a large number of line cards.

All input clocks are continuously monitored for frequency accuracy and activity.
