The CS61581 combines the com- plete analog transmit and receive circuitry for a single, full-duplex interface at T1 and E1 rates. The device is pin and function compatible with the Level One LXT310 and LXT318 (the latter in the host mode only). The de- vice can also replace LXT359 and LXT360. Enhanced functionality is available through an extended register set allowing short haul operation, custom pulse shape generation, QRSS pattern generation, detection and er- ror counting, and generation and detection of loop up and loop down codes. The CS61581 features Crystal® low-power impedance-matched line drivers and crystal- less jitter attenuation.
