TA1296FN

TA1296FN Preliminary TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic 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.DataSheet4U.com dissipation, while the compact 30-pin SSOP package allows the tuner to be kept small.
