The digital input interface must be selected to either PCM or I
in the configuration register. The compression format must also be selected with bits (LAW1 – LAW0)
in the configuration registers.
The external clock input signal on pin MCLK and the internal clock dividers must be set to values
supporting the selected digital input signal.
The digital smoothing and interpolation filter runs at 3.4 kHz and feeds the ΣΔ D/A converter that can
be switched off to conserve power and reduce noise using the D/A power down bit (DAPD).
The analog output amplifier gain is controlled from configuration registers bits (COG2 – COG0) from -
8 dB to +6 dB.
The ISD5216 has two Master Clock configuration bits that allow four possible Master Clock
frequencies. Bits CKD2 and CKDV set the Master Clock Division ratios. These are bits D12 and D8 of
CFG2, respectively. The combination of these bits, with the sample rate bit HSR0, also set the
CODEC sample frequency as shown in the following table.
