bus output or input. Unless otherwise noted, the analog input is a 0 dBm0, 1020 Hz sine wave. 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 values are tested at VDD
= 3.3 V and T
