Transmit Path Signal Processing
8.6.1
General Description
In the transmit path, data is first sent by the host DSP through a serial interface to the 73M1x66B then
interpolated by an interpolation filter, serialized and transmitted across barrier interface to the Line-Side
Device, which is floating relative to the Host-Side Device earth ground. The data received on the
Line-Side Device is then de-serialized and digitally sigma-delta modulated to a one-bit data stream of
1.536 Mbps for a sample frequency of 8 kHz or 3.072 Mbps for a sample frequency of 16 kHz. The signal
is further filtered first by a switched capacitor filter and then a continuous time anti-aliasing circuit.
The 0.2 dB pass-band ripple frequency is from dc to 3.422 kHz for an 8 kHz sample rate or 6.844 kHz
for a 16 kHz sample rate.
The 3 dB bandwidth is 3.65 kHz for an 8 kHz sample rate or 7.299 kHz for a 16 kHz sample rate.

Total Transmit Path Response
Figure 26 and Figure 27 show the transmit path frequency response. The response shape is the same,
but the frequencies double for a 16 kHz sample rate.
