COMPATIBILITY WITH THE PCM1804
Although the PCM4202 and PCM1804 are pin- and
function-compatible, there are a few differences between
the two devices that the designer should be aware of.
These differences are noted here for clarity.
D The full-scale input of the PCM4202 is 6.0V_PP
differential, while it is 5.0V_PP for the PCM1804. This
is a result of the PCM4202 having an internal +3.0V
voltage reference, and the PCM1804 having an
internal +2.5V voltage reference.
D The PCM1804 includes +5V tolerant digital inputs.
The PCM4202 does not include these because the
digital inputs are designed for interfacing to +3.3V
logic.
D The reset pin (RST) pin of the PCM4202 has an
internal pull-up resistor. For the PCM1804, this pin
has an internal pull-down resistor.

D When operating in Master mode with Single Rate
sampling selected, the audio serial port bit clock
(BCK) is equal to 64f_S for the PCM1804, while the
BCK rate is equal to 128f_S for the PCM4202.
D The following pins on the PCM4202 and PCM1804
have different names, but they perform the same
functions.
