ZHCSMU9A December 2020 – September 2021 TAS2764
PRODUCTION DATA
The TAS2764 has a diagnostic generator that can be used without any clocking applied to the device. If DG_CLK register bit is set low, an internal oscillator is used to generate the test patterns selected by DG_SIG[4:0] register bits. For sine-wave generation the sampling frequency fs should be first set using the SAMP_RATE[2:0] register bits.
The programable DC level for diagnostic mode can be set using the DG_DC[31:0] register bits.
To play a DC diagnostic tone set the bits HPF_FREQ_PB[2:0] in register 0x04 to 0h (disabled DC blocker).
