LC72122V
PLL Frequency Synthesizer
for Portable Equipment Electronic Tuning
Overview
The LC72122V is a low-voltage (1.8 to 3.6 V) PLL
frequency synthesizer IC that allows portable TV
(VHF)/FM/AM tuners to be constructed easily.

* Note : Recommended crystal oscillator CI value : CI ≤ 35 kΩ (for a 75kHz crystal )
The circuit constants for the crystal oscillator circuit depend on the crystal used, the printed sircuit board pattem, and other items. Therefore we
recommend consulting with the manfacturer of the crystal for evaluation and reliability.
The extremely high input impedance of the XIN pins means that applications must take the possibility of leakage into account.
