Design Examples
The following reference schematics show the complete Le9500 SLIC schematic for interfaces to Broadcom codecs.
Le9500/Broadcom
The following reference circuit shows the complete Le9500 SLIC device schematic for interface to the Broadcom BCM3352 as
designed on the Broadcom BCM93352SV application reference design and board. This circuit has a 600-Ω AC termination. The
BCM3351, BCM3352, and BCM6352 have programmable registers to modify the external 600-Ω termination to achieve
worldwide real or complex terminations. For complex terminations with BCM1101, the external circuit must be changed to set the
complex termination. Other resistive terminations require a change to this circuit. Contact your Zarlink account representative
for assistance with modifications to this circuit.
