M28323
3-Port DS3/E3/STS-1 Digital Jitter-Attenuator & STS-1 to DS3/E3 Desynchronizer (Not Recommended for new designs)
Description
This high density, low power solution is designed for transmission applications including add/drop multiplexers, routers, ATM multi-service switches, digital cross connects, and DS3 to STS-1 mappers.The M28320 12-port DJAT device can be combined with Line Interface Units (LIUs) and mapper devices in addressing traffic-aggregation equipment needs in converting high-speed Synchronous Transport Signal-1 (STS-1) streams to asynchronous lower speed DS3/E3 data rates for systems used in data centers and Points of Presence (POPs).
The M28320 12-port DJAT leverages Mindspeed's advance digital signal processing techniques along, with extensive knowledge of analog mixed signal design, that provide the first solution of its kind to adapt and fully smooth a STS-1 clock (with overhead gaps) to a network compliant DS3 or E3 line clock.
Features
- High density: up to 12 independent jitter-attenuators and desynchronizers for DS3/ E3 and STS-1 in one package
- Low power: <350 mW maximum power consumption
- Crystal-less jitter attenuation
- Two PRBS generator/detector per channel
- Ability to dejitter AMI or NRZ input data
- Ability to independently bypass the JAT for each channel
- Single 3.3 V supply
- Complies with Telecordia GR-253 and GR-499, ETSI TBR-24 and ANSI T1.105.03b as well as ITU-T G.751, G755, G783 and G.823 standards
- Programmable FIFO depth optimal for SONET/SDH
- Programmable clocking of both inputs and outputs on either edge
- One second timer for event latching
- Power-down control for each channel
- Small 15 mm BGA package
