The CS4344 family members (CS4344, CS4345, and

CS4348) are complete, stereo digital-to-analog output

systems including interpolation, multibit D/A conversion

and output analog filtering in a 10-pin package. The

CS4344 family supports major audio data interface formats.

Individual devices differ only in the supported

interface format.

The CS4344 family is based on a fourth-order multibit

delta-sigma modulator with a linear analog low-pass filter.

This family also includes autospeed mode detection

using both sample rate and master clock ratio as a

method of auto-selecting sampling rates between 2 kHz

and 200 kHz.

The CS4344 family contains on-chip digital deemphasis,

operates from a single +3.3 V or +5 V power supply,

and requires minimal support circuitry. These features

are ideal for DVD players & recorders, digital televisions,

home theater and set top box products, and

automotive audio systems.

The CS4344 family is available in a 10-pin TSSOP

package in both Commercial (-10 to +85 °C) and Automotive

grades (-40 to +85 °C). See Section 8. “Ordering

Information” on page 23 for complete details.

11. Not all sample rates are supported for all clock ratios. See Table 1, “Common Clock Frequencies,” on

page 12 for supported ratio’s and frequencies.

12. In Internal SCLK Mode, the Duty Cycle must be 50% 1/2 MCLK Period.
