8.3.9 Digital PDM Microphone Record Channel
In addition to supporting analog microphones, the device also interfaces to digital pulse-density-modulation
(PDM) microphones and uses high-order and high-performance decimation filters to generate pulse code
modulation (PCM) output data that can be transmitted on the audio serial interface to the host. If analog
microphones are not used in the system, then the analog input pins (INxP and INxM) can be repurposed as the
GPIx and GPOx pins respectively and can be configured for the PDMDINx and PDMCLK clocks for digital PDM
microphone recording. The device supports up to eight digital microphone recording channels.
The device internally generates PCMCLK with a programmable frequency of either 6.144 MHz, 3.072 MHz,
1.536 MHz, or 768 kHz (for output data sample rates in multiples or submultiples of 48 kHz) or 5.6448 MHz,
2.8224 MHz, 1.4112 MHz, or 705.6 kHz (for output data sample rates in multiples or submultiples of 44.1 kHz)
using the PDMCLK_DIV[1:0], P0_R31_D[1:0] register bits. PDMCLK can be routed on the GPOx pin. This clock
can be connected to the external digital microphone device. Figure 78 shows a connection diagram of the digital
PDM microphones.
Figure 78. Digital PDM Microphones Connection Diagram to the TLV320ADC6140
The single-bit output of the external digital microphone device can be connected to the GPIx pin. This single data
line can be shared by two digital microphones to place their data on the opposite edge of PDMCLK. Internally,
the device latches the steady value of the data on the rising edge of PDMCLK or the falling edge of PDMCLK
based on the configuration register bits set in P0_R32_D[7:4]. Figure 79 shows the digital PDM microphone
interface timing diagram.
Figure 79. Digital PDM Microphone Protocol Timing Diagram
When the digital microphone is used for recording, the analog blocks of the respective ADC channel are powered
down and bypassed for power efficiency. Use the CH1_INSRC[1:0] (P0_R60_D[6:5]), CH2_INSRC[1:0]
(P0_R65_D[6:5]), CH3_INSRC[1:0] (P0_R70_D[6:5]), and CH4_INSRC[1:0] (P0_R75_D[6:5]) register bits to
select the analog microphone or digital microphone for channel 1 to channel 4.
