Le9500/Broadcom
The following reference schematic shows the complete Le9500 SLIC device schematic for interface to the Broadcom BCM3367/
3368. This circuit has a natural 700-Ω AC termination impedance. The BCM3367 or MCB3368 has programmable registers to
modify the external 700-Ω termination to achieve worldwide real or complex terminations, as well as to set transmit and receive
gains, and other AC parameters. The BCM3367/3368 codec also drives ringing inputs, sets SLIC operation state, and monitors
NSTAT. The voltage of the battery supply to V
states.
