IDT821024 QUAD NON-PROGRAMMABLE PCM CODEC
TRANSMISSION CHARACTERISTICS
dBm0, 1020 Hz sine wave; the input amplifier is set for unity gain. The digital input is a PCM bit stream equivalent to that obtained by passing a 0
dBm0, 1020 Hz sine wave through an ideal encoder. The output level is sin(x)/x-corrected. Typical value are tested at V

Frequency Response
Group Delay
0dBm0 is defined as 0.6832Vrms for A-law and 0.6778 Vrms for -law, both for 600
Note*: Minimum value in transmit and receive path.
