Slave Mode
As a slave, the TLC320AD58C receives LRClk, Fsync, and SCLK as inputs. The conversion cycle is
synchronized to the rising edge of LRClk, and the data is synchronized to the falling edge of SCLK. SCLK
must meet the setup requirements specified in the recommended operating conditions section.
Synchronization of the slave modes is accomplished with the digital power-down control.
In slave mode, Fsync is an input. Three modes are provided as shown in Figures 2–4(a) through 2–4(c).
SCLK and LRClk are externally generated and sourced. The first rising edges of SCLK and LRClk after a
power-down cycle initiate the conversion cycle. Refer to the master-mode section for signal functions.
