Zarlink Semiconductor Inc.
A SLIC Device Evaluation Board is connected to one of the four available channels of the QLSLAC
device. The evaluation board has four pairs of BNC connectors, VIN1 - VIN4 and VOUT1 - VOUT4,
representing the analog inputs and outputs of the QLSLAC device's channels. These are connected
directly to the SLIC device's corresponding VTX and VRX BNC connectors. Control of the SLIC
device is provided via the digital control headers (H1 - H4). The 20-pin interconnect cable that is
provided with a
Zarlink
SLIC Device Evaluation Board can be plugged into any of the four headers
enabling quick and easy control of the SLIC device.
Test equipment can be connected to the tip/ring connectors of the SLIC Device Evaluation Board,
or it can be connected directly to the analog input/output of the evaluation board, bypassing the
SLIC device entirely. Digital PCM or T1/E1 access to test equipment is provided through either the
VP Demo Board or the ACIF2-A board.

DIGITAL INTERFACE
All PCM/MPI interface signals pass through IFB0, the 50-pin connector, from either the ACIF2-A
board or the VP Demo Board to the QLSLAC Device Evaluation Board. The Le58QL021 device
operates in a PCM data communication mode with a microprocessor control interface (PCM/MPI
mode). The Le58QL061 device is designed to operate in the PCM/MPI mode or in the General
Control Interface (GCI) mode. The table below lists the pin assignments for PCM and GCI modes.
When used in the GCI mode, some of these control signals have their functions redefined, as noted
by the shaded cells.
