• Description: High Feature 192khz 24bit Digital Audio Interface Transceiver
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
The AK4115 has two transmitter outputs, TX0 and TX1. TX0 is a loop-through output that is selected from the RX input.
TX0 output is selected from RX7-0 by the OPS00, OPS01 and OPS02 bits. In parallel mode, the source of the
loop-through output from TX0 is fixed to RX0.
TX1 accepts output from RX7-0 or the transmitter (DIT; the data from DAUX is transformed to IEC60958 format.). TX1
also has a true RS422 line driver (differential output). The source of the loop-through output from TX1 is selected from
RX7-0 by the OPS10, OPS11 and OPS12 bits. When the DIT bit is set to “1”, TX1 is transmitted to DAUX data. In
parallel mode, TX1 is fixed to DIT.
