BU1920 : BU1920 / BU1920F / BU1920FS 172 Audio ICs FInput / output circuits BU1920 / BU1920F / BU1920FS 173 Audio ICs BU1920 / BU1920F / BU1920FS FElectrical characteristics (unless otherwise noted, Ta = 25_C, VDD = 5.0V and GND = 0.0V) Filter block Demodulator block 174 Audio ICs FOutput data timing BU1920 / BU1920F / BU1920FS The clock (RCLK) frequency is 1187.5Hz. Depending on the state of the internal PLL clock, the data (RDATA) is replaced in synchronous with either the rising or falling edge of the clock. To read the data, you may choose either the rising or falling edge of the clock as the reference. The data is valid for 416.7µs, after the reference clock edge. QUAL pin opera.
