1 / 21 page TA1322FN 2002-02-12 1 TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA1322FN Down-Converter IC with PLL for Satellite Tuner 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 I2C 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. Features · Supply voltage: 5.0 V (typ.) · Wide input frequency range · Low phase noise oscillator · Standard I2C bus format control · 4-MHz (X’tal) buffer output pin · Reference oscillator input change-over switch [X’tal or external input] · 33-V high-voltage tuning amplifier built-in · Built-in comparator (P4, P5, P7) · Bandswitch drive transistor (P0) [IBD = 40 mA (max)] · Selected IF output port · Frequency step: 62.5 kHz or 125 kHz (for 4-MHz X’tal) · 4-address setting via address selector · Power-on reset circuit · ×1/2 prescaler · Flat compact package: SSOP30-P-300-0.65 (0.65-mm pitch) Power-On Reset Operation Conditions · Frequency step: 125 kHz · Charge pump output current: ±50 µA · Counter data: all [0] · Band driver: OFF · Tuning amplifier: OFF · IF output operation: pin 19 is ON Note 1: This device can easily be damaged by high voltages or electrical fields. For this reason, please handle it with care. Weight: 0.17 g (typ.) Preliminary |
