Description
The CS4362 is a complete 6-channel digital-to-analog system including digital interpolation, fifth-order deltasigma digital-to-analog conversion, digital de-emphasis, volume control and analog filtering. The advantages of this architecture include: ideal differential linearity, no distortion mechanisms due to resistor matching errors, no linearity drift over time and temperature and a high tolerance to clock jitter. The CS4362 is available in a 48-pin LQFP package in Commercial grade (-10°C to +70°C). The CDB4362 Customer Demonstration Board is also available for device evaluation and implementation suggestions. Please see “Ordering Information” on page 42 for complete details. The CS4362 accepts PCM data at sample rates from 4 kHz to 192 kHz, DSD audio data, and operates over a wide power supply range. These features are ideal for multi-channel audio systems including DVD players. SACD players, A/V receivers, digital TV’s, mixing consoles, and effects processors.

Notes: 4. VFS is tested under load RL and includes attenuation due to ZOUT 5. Current consumption increases with increasing FS within a given speed mode and is signal dependant. Max values are based on highest FS and highest MCLK. 6. ILC measured with no external loading on the SDA pin. 7. This specification is violated when the VLC supply is greater than VD and when pin 16 (M1/SDA) is tied or pulled low. Logic tied to pin 16 needs to be able to sink this current. 8. Power Down Mode is defined as RST pin = Low with all clock and data lines held static. 9. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figures 5 and 6.

Notes: 10. Slow Roll-Off interpolation filter is only available in Control Port Mode. 11. Filter response is not tested but is guaranteed by design. 12. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 9 to 32) have been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs. 13. Single- and Double-Speed Mode Measurement Bandwidth is from stopband to 3 Fs. Quad-Speed Mode Measurement Bandwidth is from stopband to 1.34 Fs. 14. De-emphasis is available only in Single-Speed Mode; Only 44.1 kHz De-emphasis is available in StandAlone Mode.
