TA1296FN
Down-Converter IC with PLL for Satellite Tuner
The TA1296FN 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 I2C bus data format is used as the data control format.
The supply voltage of 5.0 V helps minimize the tuner’s power
www.DataSheetd4iUs.sciopmation, while the compact 30-pin SSOP package allows the
tuner to be kept small.
