Description
The MT90401AB is a Telecommunication Interface ICs digital phase locked loop (DPLL) designed for synchronizing SDH (Synchronous Digital Hierarchy) and SONET (Synchronous Optical Network) networking equipment. It guarantees that the timing of outgoing signals falls within the limits specified by Telcordia, ANSI, and the ITU during normal operation and in the presence of disturbances on the incoming synchronization signals.
Specifications and features
- Meets requirements of GR-253-CORE for SONET Stratum 3 and SONET minimum clock
- Meets requirements of GR-1244-CORE Stratum 3
- Meets requirements of G.813 Option 1 and Option 2 for SDH Equipment Clocks (SEC) with external jitter attenuator
- Provides OC-3/STM-1, DS3, E3, 19.44 MHz, DS2, E1, T1, 8 kHz, and ST-BUS clock outputs
- Accepts reference inputs from two independent sources
- Selectable 1.544 MHz, 2.048 MHz, 19.44 MHz, or 8kHz input reference frequencies
- Holdover accuracy of 0.02 ppm
- Adjustable output clock phase supporting master-slave arrangements
- Hardware or microprocessor control (8-bit microprocessor interface)
- 3.3 V supply
- JTAG boundary scan
Application Scenarios
The MT90401AB is used in various applications, including:
- SONET/SDH Add/Drop multiplexers
- SONET/SDH uplinks
- Integrated access devices
- ATM edge switches
