Figure 3. Serial Data Interface Timing
The audio serial interface for the TPA5051 consists of two 3-wire synchronous serial ports. Each includes an
LRCLK, BCLK, and DATA. BCLK is the serial audio bit clock, and it is used to clock the serial data present on
the DATA line into the serial shift register of the audio interface. Serial data is clocked into the TPA5051 on the
rising edge of BCLK. LRCLK is the serial audio left/right word clock, operated at the sampling frequency, fs. It is
used to latch serial data into the internal registers of the serial audio interface. BCLK can be operated at 32 to
64 times the sampling frequency for right-justified, left-justified, and I2S formats. Generally, both LRCLK and
BCLK should be synchronous to the system clock. However, the TPA5051 does not have a system clock, so the
only synchonization necessary is between BCLK and LRCLK.
The TPA5051 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
