SDA4330-2X SDA4330-2X

The SDA 4330-2X is a radio PLL controlled via I2C Bus for frequency synthesis in the AM and FM range. It includes an IF counter up to 50 MHz enabling a precise search tuning stop. 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, .
