DESCRIPTION
The PCM1716 is designed for Mid to High grade
Digital Audio applications which achieve 96kHz sam-
pling rates with 24-bit audio data. PCM1716 uses a
newly developed, enhanced multi-level delta-sigma
modulator architecture that improves audio dynamic
performance and reduces jitter sensitivity in actual
applications.
The internal digital filter operates at 8x over sampling
at a 96kHz sampling rate, with two kinds of roll-off
performances that can be selected: sharp roll-off, or
slow roll-off, as required for specific applications.
PCM1716 is suitable for Mid to High grade audio
applications such as CD, DVD-Audio, and Music
Instruments, since the device has superior audio
dynamic performance, 24-bit resolution and 96kHz
sampling.

forced to a bipolar zero state (VCC/ 2). The zero detection
feature is used to avoid noise which may occur when the
input is DC. When the output is forced to bipolar zero,
there may be an audible click. PCM1716 allows the zero
detect feature to be disabled so the user can implement an
external muting circuit.

ATC (B2) is used as an attenuation control. When bit 3 is
set HIGH, the attenuation data on Register 0 is used for
both channels, and the data in Register 1 is ignored. When
bit 3 is LOW, each channel has separate attenuation data.
ATC = L
ATC = H

Bits 0 (I2S) and 1 (LRP) are used to control the input data
format. A “LOW” on bit 0 sets the format to (MSB-first,
right-justified Japanese format) and a “HIGH” sets the
format to I2S (Philips serial data protocol). Bit 1 (LRP) is
used to select the polarity of LRCIN (sample rate clock).
When bit 1 is “LOW”, left channel data is assumed when
LRCIN is in a “HIGH” phase and right channel data is
assumed when LRCIN is in a “LOW” phase. When bit 1 is
“HIGH”, the polarity assumption is reversed.
