5 / 18 page TAS5001 SLES009A – SEPTEMBER 2001 – REVISED DECEMBER 2001 5 www.ti.com functional description serial audio port The serial audio port consists of a shift clock (SCLK pin), a left/right frame synchronization clock (LRCLK pin), and a data input (SDIN pin). The serial audio port supports standard serial PCM formats (Fs = 32-kHz, 44.1-kHz, 48-kHz, 88.2-kHz, 96-kHz stereo). See the serial interface formats section for more information. system clocks—master mode and slave mode The TAS5001 allows multiple system clocking schemes. Master mode indicates that the TAS5001 provides system clocks to other parts of the system (M_S=1). Audio system clocks of frequency 256 Fs MCLK_OUT, 64 Fs SCLK, and Fs LRCLK are output from this device when it is configured in master mode. Slave mode indicates that a system master other than the TAS5001 provides system clocks (LRCLK, SCLK, and MCLK_IN) to the TAS5001 (M_S = 0). The TAS5001 operates with LRCLK and SCLK synchronized to MCLK. TAS5001 does not require any specific phase relationship between LRCLK and MCLK, but there must be synchronization. In the slave mode MCLK_OUT is driven low. Table 1 shows all the possible master and slave modes. oscillator/sampling frequency The sampling frequency is determined by the crystal (master mode) or master clock in (slave mode) which should be either 8.192 MHz (Fs = 32 kHz), 11.2896 MHz (Fs = 44.1 kHz), or 12.288 MHz (Fs = 48 kHz). Twice the normal sampling frequency can be selected by using the DBSPD pin which allows usage of Fs = 88.2 kHz or Fs = 96 kHz. In the double-speed slave mode (DBSPD = 1, M_S = 0), the external clock input is either 22.5796 MHz (Fs = 88.2 kHz) or 24.576 MHz (Fs = 96 kHz). Note that 32-kHz sampling is supported in the normal speed modes. Table 1 explains the proper clock selection. Table 1.

Connections for the PLL external loop filter are provided as PLL_FLT_RET and PLL_FLT_OUT. If the PLL loses lock, the PWM output status pins (VALID_L and VALID_R) go low. Note that VALID_L and VALID_R can go low for other conditions as well. See the error status reporting section for more information. |
