FPGA SAA7220 Replaces Digital Filter DF7220 DF7220S1 Module NOS/4X/8X Conversion 192k/384k

FPGA SAA7220 Replaces Digital Filter DF7220 DF7220S1 Module NOS/4X/8X Conversion 192k/384k Kuvaus

1. Adopting a 4-layer PCB, fully compatible for various versions of TDA1541 and TDA1541a, compatible for TDA1387 and TDA1543, and supporting CD players.



2.2 Modes: NOS and OS.

3. NOS mode supports to 24bit 384kHz input

4. OS mode supports to 24 bit 384kHz input

5. OS mode can choose 4x or 8x oversampling; 4x mode output with a sampling rate of 176.4/192kHz, used for I2S format of 1541/1543; Output 352.8/384kHz sampling rate in 8x mode, used for synchronous data format of 1541 and I2S format of 1387.

6. The Pierce oscillator is composed of pins xi/xo and supports passive crystal oscillators

7. The main clock input of pin 1 supports 11.2896-49.152MHz and 16.9344/18.432MHz.

8. NOS mode only performs timing shaping and data rearrangement I2S signals, without any DSP operations.

9. The NOS mode divides the input 64 times wck bck by 2, resulting in an output bcko of only 32 times wck. By rearranging the data through registers, the 2 * 32-bit standard I2s format is converted to the 2 * 16 bit I2s format required by TDA1541A, enabling NOS output of 352.8/384kHz data.
