Description
The CS61318 is an E1 primary rate line interface unit. This device combines the complete analog transmit and receive circuitry for a single, full-duplex interface E1 rates. The device provides jitter attenuation compliant to CTR12/TBR13 without requiring an external crystal. Also, the CS61318 is pin and function compatible with the Level One LXT318.
