OPERATION OVERVIEW (ADC/DAC part, DIR/DIT part)
Serial
Control
Interface
AK4588 has two registers, which are ADC/DAC part (AK4628 compatible) and DIR/DIT part (AK4114 compatible).
Each register is set by chip address pin.
(1). 4-wire serial control mode (I2C pin = “L”)
The internal registers may be either written or read by the 4-wire
μ
P interface pins: CSN, CCLK, CDTI & CDTO. The
data on this interface consists of Chip address (2bits, ADC/DAC part register is set by CAD1/0 pins. DIR/DIT part C1-0
bits are fixed to “00”), Read/Write (1bit), Register address (MSB first, 5bits) and Control data (MSB first, 8bits).
Address and data is clocked in on the rising edge of CCLK and data is clocked out on the falling edge. For write
operations, data is latched after the 16th rising edge of CCLK, after a high-to-low transition of CSN. For read
operations, the CDTO output goes high impedance after a low-to-high transition of CSN. The maximum speed of
CCLK is 5MHz. PDN pin = “L” resets the registers to their default values. When the state of P/S pin is changed, the
AK4588 should be reset by PDN pin = “L”. Register of ADC/DAC part can not read.
