Serial Data Interface Timing The audio serial interface for the TPA5050 consists of a 3-wire synchronous serial port. It includes LRCLK, BCLK, and DATA. BCLK is the serial audio bit clock, and it is used to clock the serial data present on DATA into the serial shift register of the audio interface. Serial data is clocked into the TPA5050 on the rising edge of BCLK. LRCLK is the serial audio left/right word clock. It is used to latch serial data into the internal registers of the serial audio interface. LRCLK is operated at the sampling frequency, fs. BCLK can be operated at 32 to 64 times the sampling frequency for right-justified, left-justified, and I2S formats. A system clock is not necessary for the operation of the TPA5050. The TPA5050 supports industry-standard audio data formats, including right-justified, I2S, and left-justified. The data formats are shown in Figure 4. Data formats are selected using the I2C interface and register map (see Table 1). 5 Submit Documentation Feedback |
