FUNCTIONAL DESCRIPTIONS
Zero Detect
The DSD1793 has a zero-detect function. When the DSD1793 detects the zero conditions as shown in Table 2, the
DSD1793 sets ZEROL (pin 23) and ZEROR (pin 22) to HIGH.

MODE
DETECTING CONDITION AND TIME
PCM
DATA is continuously LOW for 1024 LRCKs.
External DF mode
DATA is continuously LOW for 8
× 1024 WDCKs.
DSD
DZ0
There are an equal number of 1s and 0s in every 8 bits of DSD input data for 23 ms.
DSD
DZ1
The input data is 1001 0110 continuously for 23 ms.
Serial Control Interface (I2C)
The DSD1793 supports the I2C serial bus and the data transmission protocol for standard and fast mode as a slave
device. This protocol is explained in I2C specification 2.0.

R/W
The DSD1793 has 7 bits for its own slave address. The first five bits (MSBs) of the slave address are factory preset
to 10011. The next two bits of the address byte are the device select bits, which can be user-defined by the ADR1
and ADR0 terminals. A maximum of four DSD1793s can be connected on the same bus at one time. Each DSD1793
responds when it receives its own slave address.
Packet Protocol
A master device must control packet protocol, which consists of start condition, slave address, read/write bit, data
if write or acknowledge if read, and stop condition. The DSD1793 supports only slave receivers and slave
transmitters.
