Description
The CS4334 family members are complete, stereo dig-
ital-to-analog output systems including interpolation,
1-bit D/A conversion and output analog filtering in an
8-pin package. The CS4334/5/8/9 support all major au-
dio data interface formats, and the individual devices
differ only in the supported interface format.
The CS4334 family is based on Delta-Sigma modula-
tion, where the modulator output controls the reference
voltage input to an ultra-linear analog low-pass filter.
This architecture allows for infinite adjustment of sam-
ple rate between 2 kHz and 100 kHz simply by
changing the master clock frequency.
The CS4334 family contains on-chip digital de-empha-
sis, operates from a single +5V power supply, and
requires minimal support circuitry. These features are
ideal for set-top boxes, DVD players, SVCD players,
and A/V receivers.

    ... The CS4334 family of devices supports two modes of operation. The devices operate in Base Rate Mode (BRM) when MCLK/LRCK is 256, 384 or 512 and in High Rate Mode (HRM) when MCLK/LRCK is 128 or 192. High Rate Mode allows input sample rates up to 100 kHz ...

    ... SYSTEM DESIGN The CS4334 family accepts data at standard audio sample rates including 48, 44.1 and 32 kHz in BRM and 96, 88.2 and 64 kHz in HRM. Audio data is input via the serial data input pin (SDATA). The Left/Right Clock (LRCK) defines the channel and delineation of data, and the Serial Clock (SCLK) clocks audio data into the input data buffer. The CS4334/5/8/9 differ in serial data formats as shown in 4 ...

    ... Q 4.5 Output Transient Control The CS4334 family uses Popguard® technology to minimize the effects of output transients during power- up and power-down. This technique eliminates the audio transients commonly produced by single-ended single-supply converters when it is implemented with external DC-blocking capacitors connected in series with the audio outputs. To make best use of this feature necessary to understand its operation. ...
