DS26503 - T1/E1/J1 BITS Element

General Description

The DS26503 is a building-integrated timingsupply (BITS) clock-recovery element.

The receiver portion can recover a clock from T1, E1, and 6312kHz synchronization timing interfaces.

In T1 and E1 modes, the Synchronization Status Message (SSM) can also be recovered.

Key Features

  • G.703 2048kHz Synchronization Interface Compliant.
  • G.703 6312kHz Japanese Synchronization Interface Compliant.
  • Interfaces to Standard T1/J1 (1.544MHz) and E1 (2.048MHz).
  • Interface to CMI-Coded T1/J1 and E1.
  • Short- and Long-Haul Line Interface.
  • Transmit and Receive T1 and E1 SSM Messages with Message Validation.
  • Crystal-Less Jitter Attenuator with Bypass Mode.
  • Fully Independent Transmit and Receive Functionality.
  • Internal Software-Selectable Receive-.

DS26503 T1/E1/J1 BITS Element www.maxim-ic.com GENERAL DESCRIPTION The DS26503 is a building-integrated timingsupply (BITS) clock-recovery element. The receiver portion can recover a clock from T1, E1, and 6312kHz synchronization timing interfaces. In T1 and E1 modes, the Synchronization Status Message (SSM) can also be recovered. The transmit portion can directly interface to T1 or E1 interfaces as well as source the SSM in T1 and E1 modes. The DS26503 can translate between any of the supported inbound synchronization clock rates to any supported outbound rate. A separate output is provided to source a 6312kHz clock. The device is controlled through a parallel, serial, or hardware controller port. FEATURES § G.703 2048kHz Synchronization Interface Compliant § G.
