ZHCSIM2D June 2010 – August 2021 PCM9211
PRODUCTION DATA
The PCM9211 can also be used to suppress the jitter of the DSCKI signals, typically generated by an HDMI receiver. DSD signals (DBCKI, DSDRI, DSDLI) are routed to the Main Port as DBCKO, DSDRO, and DSDLO, respectively.
The DIT works with DSCKI for SCK, DBCKI for BCK, internally-created LRCK, DBCKI divided by 64, and 0 data for DIN.
MOLRMTEN (Register 6Ah) can be used to mute/unmute DSDRO from the LRCK port. When MOLRMTEN is set to 1, mute/unmute of DSDRO from LRCK is available by MODMUT = 1/0.
Table 7-30 summarizes the DSD input mode configuration. Figure 7-24 illustrates the DSD format.
SIGNAL NAME | MPIO GROUP / PIN | DESCRIPTION |
---|---|---|
DSCKI | MPIO_C0 or MPIO_B0 | SCK input (256fS) |
DBCKI | MPIO_C1 or MPIO_B1 | DBCK input for DSD format (64fS) |
DSDRI | MPIO_C2 or MPIO_B2 | R-channel DSD data input for DSD format |
DSDLI | MPIO_C3 or MPIO_B3 | L-channel DSD data input for DSD format |
DSCKO | SCKO | SCK output generated by DIR from DIT output |
DBCKO | BCK | DBCK output for DSD format (the same signal as DBCKI) |
DSDRO | LRCK | R-channel DSD data output for DSD format (the same signal as DSDRI) |
DSDLO | DOUT | L-channel DSD data output for DSD format(the same signal as DSDLI) |
