AKD7782-A Datasheet, PDF (5/73 Pages) Asahi Kasei Microsystems – AK7782 Evaluation Board Rev.0

[AKD7782-A]
(1) Evaluation mode of ADC using DIT of AK4118A : CKM Master Mode = 0
SPDIF-OUT is used. Set the clock mode of AK7782 to Master Mode 0 (12.288MHz).
AK7782 supplies MCLK, BICK, and LRCK to AK4118A and AK4118A outputs the data from ADC1, ADC2 and
ADCM.

For ADC1 and ADC2, RCA1/RCA2 or RCA3/RCA4 are available. Please refer to Table 5 for the setting of
jumpers which used to select input channels.
For ADCM, RCA5(AINM) is available.
(2) Evaluation mode of DSP using DIR/DIT of AK4118A : CKM Slave Mode = 2/4/5
SPDIF-IN and SPDIF-OUT are used. Set the clock mode of AK7782 to Master Mode 2/4/5.
AK4118A supplies MCLK, BICK, LRCK and digital data to AK7782 and outputs data from AK7782.
(MCLK is needed when CKM Slave Mode = 2.)

(JP101 is needed only when CKM Mode = 2)
(3) Evaluation mode of SRC using DIR of AK4118A and SMUX port : CKM Master Mode = 0
SPDIF-OUT and SMUX PORT are used. Set the clock mode of AK7782 to Master Mode 0 (12.288MHz).
SMUX PORT is used as input and supplies BICK, LRCK and digital data to SRC of AK7782.
AK7782 supplies MCLK, BICK, and LRCK to AK4118A and AK4118A outputs the data from SRC.

Crystal of 12.288MHz is equipped on the sub board for frequencies of 48kHz series. Please change the cystal to
11.2896MHz when using 44.1kHz series’s frequencies.
[Connection of other connectors]
SMUX PORT 1 or PORT 2 is available. Please refer to Table 1 about the pin assignment of SMUX port.
