Access to the MAX9850 analog inputs and outputs, is

provided through RCA jacks J3–J6. Access the

MAX9850 headphone outputs through the headphone

jack J8 or the provided LEFT, RIGHT, and GND pads.

The EV kit also features on-board level translators that

allow the on-board S/PDIF receiver to communicate

age range (1.8V to 3.6V). The CMOD232 command

module powers half of the on-board level translators.

For optimum performance, digital audio systems

require a stable frequency source. The MAX9850 EV kit

features an on-board 12MHz crystal oscillator. In addi-

tion, the MAX9850 EV kit can also use a user-provided

signal source that is connected to J9. Alternatively, the

S/PDIF recovered clock can be used. The MAX9850 ev

kit software controls which clock signal is routed to the

MCLK input (see the

Clock Setup section for more

details).
