Analog output of the receiver filter
Vcc = +5V + 5%
Receive frame sync pulse. 8KHz pulse train.
PCM data input
Logic input which selects either 1.536MHz / 1.544MHz or 2.048MHz for master
clock in normal operation and BCLKx is used for both TX and RX directions.
Alternately direct clock input available, vary from 64KHz to 2.048MHz.
When MCLK
Normally connected continuously low, MCLKx is selected for all DAC timing.
Alternately direct 1.536MHz / 1.544MHz or 2.048MHz clock input is available.
1.536MHz / 1.544MHz or 2.048MHz clock input is available
May be vary from 64KHz 2.048MHz, but BCLKx is externally tied with MCLKx
in normal operation.
PCM data output.
TX frame sync pulse. 8KHz pulse train.
Changed from high to low during the encoder timeslot. Open drain output.
Analog output of the TX input amplifier.
Used to set gain through external resistor between pin 14 to pin 15.
Inverting input stage of the TX analog signal.
Non-inverting input stage of the TX analog signal.
