SDA4331 Overview
The SDA 4331X is a radio PLL controlled via I2C Bus for frequency synthesis in the AM and FM range. 3 Circuit Description The reference frequency for the PLL is derived from the quartz oscillator OSC1). The R-prescaler can be adapted to quartz frequencies of 4, 8 or 10.25 MHz, respectively, yielding an internal 50 kHz reference.
