LM4921ITL DEMO BOARD OPERATION
The LM4921ITL demo board is a complete evaluation platform (Note 10), designed to give easy access to the control pins of the
part and comprise all the necessary external passive components. There are separate analog and digital supply connectors, SPI
interface bus (J1) for the control lines, I2S interface bus (J2) for full-range digital audio, stereo headphone output (J3), and an
external MCLK input (P1) for use in place of the crystal on the demoboard.
