Product Summary

The LE58QL063HVC is a Quad Low Voltage Subscriber Line Audio-Processing Circuit. The LE58QL063HVC integrates the key functions of analog line cards into high-performance, very-programmable, four-channel codec-filter devices. It is based on the proven design of Legerity’s reliable SLAC device families. The application of the LE58QL063HVC is Codec function on telephone switch line cards.
