HDCD Filter Processed Signal Output to the D/A Converter Block
The 8
×
oversampled data (4
×
oversampled in double-speed playback) processed by the HDCD filter block is transferred
to the internal D/A converter block, converted to PWM data, and output from the LCHP, LCHN, RCHN, and RCHP pins.
This 8
×
oversampling filter output signal has had internal deemphasis filtering and attenuator processing applied.
HDCD Filter Block Source Switching — Pin 57: LRCKI, pin 61: BCKI, pin 59: DATAI, pins 32: EMPH
The signal to be processed in the HDCD filter block can be set to be either the 20-bit data from the HDCD decoder block
or external data with the XDSETL flag in the HDCD control register. If data input from outside the IC is selected as the
HDCD filter block source signal, the bit length of that data (i.e. the serial input format) can be switched as shown in the
table below using the DIN16 flag in the HDCD control register.
