Description

The CS61310 is a T1 primary rate line interface unit. It combines the complete analog transmit-and-receive circuitry for a single, full-duplex interface at T1 rates. The device is pin- and function-compatible with the Level One LXT310.

Enhanced functionality is available through an extended register set, allowing custom pulse shape generation as well as generation and detection of loop up and loop down codes. The CS61310 features crystal-less jitter attenuation.
