Update: 30 September, 2023
This document is a guide for converting existing linecard designs using Zarlink’s QSLAC™ devices to designs using the newer QLSLAC™ devices with a minimal amount of rework. The QLSLAC device is a low voltage and low power replacement for the QSLAC device. Because of the lower voltage, the analog output voltage is reduced compared to the QSLAC device, resulting in lower receive gains. Lower receive levels may be easily compensated in the Subscriber Line Interface Circuit. Zarlink recommends steps in this document that will allow full software compatibility with existing QSLAC device designs with only minor hardware modifications.
