Product Details
__
The CX28333 is a three-channel, E3/DS3/STS-1 fully-integrated Line Interface Unit (LIU). It is configured via external pins and does not need a microprocessor interface. Each channel has an independent equalizer on the receive side requiring no user configuration. Also, each channel has a programmable transmit pulse shaper that can be set to ensure that the cross- connect pulse mask requirement is met for transmit cable length up to 450 feet. The CX28332 is a dual-channel, and the CX28331 is a single-channel LIU with performance identical to the CX28333.
