PLL with I2C Bus for AM/FM Receivers SDA 4331X 1 1.1 • • • • • Overview


155 MHz FM and 40 MHz AM input frequency 30 mVeff AM and 50 mVeff FM sensitivity Additional open drain ports controlled by I2C Bus 2-pin quartz oscillator Fast phase detector with short anti-backlash pulses P-DSO-24-1 and polarity reversal • Charge pump current programmable in four steps up to 4.5 mA • Frequency resolution of 1, 5 and 10 kHz AM and 12.5, 25 and 50 kHz FM • P-DSO-24 package Type SDA 4331X 1.2 Application Ordering Code Q67100-H5139 Package P-DSO-24-1 The SDA 4331X provides separated input and output ports for AM and FM and is well suited for extremely fast loop settling times in the FM mode.
