Description

The TA1322FN is a wideband down-converter which can operate at input frequency ranging from 850 MHz to 2200 MHz. Intended primarily for use in satellite tuners, this IC includes an oscillator, a mixer, an IF amplifier and a PLL.

The I² C bus data format is used as the data control format.

The supply voltage of 5.0 V helps minimize the tuner's power dissipation, while the compact 30-pin SSOP package allows the tuner to be kept small.
