PCM2900C PCM2902C SBFS039 – SEPTEMBER 2011 www.ti.com Clock and Reset The PCM2900C/2902C requires a 12-MHz (±500 ppm) clock for the USB and audio functions, which can be generated by a built-in crystal oscillator with a 12-MHz crystal resonator. The 12-MHz crystal resonator must be connected to XTI (pin 21) and XTO (pin 20) with one high (1-MΩ) resistor and two small capacitors, the capacitance of which depends on the load capacitance of the crystal resonator.
