TD7104FG
TOSHIBA Bipolar Digital Integrated Circuit Silicon Monolithic
TD7104FG
ECL Prescaler for Digital Synthesized Tuner
The TD7104FG is a general-purpose fixed dividing prescaler developed for digital tuning system of the PLL frequency synthesizer type, and can operate at up to 1 GHz.
Features
* * * Maximum operating frequency 1 GHz (at 1 / 8 dividing mode) Dividing ratios of 1 / 8, 1 / 4, and 1 / 2 are available. Independent TV and FM inputs are provided. In FM mode, this IC can function as a buffer amplifier (1 / 1 dividing). * * The built in input amplifier contributes to realizing high input voltage sensitivity. Built in standby circuit Weight P-SOP8- 225-1.27 : 76 mg (typ.)

Pin Function
Pin No. 1 Symbol VCC FMIN Pin Name Power supply terminal FM local OSC. signal input terminal Function And Description Applies voltage of VCC = 3.0 to 5.5V Inputs local oscillation signal in FM band. fIN = 50 to 200MHz, FMIN input signal is output by a 1 / 1 dividing ratio (buffer amplifier). Inputs local oscillation signal in TV band. FIN = 50M to 1.0GHz, TVIN input signal is output by a 1 / 8, 1 / 4, or 1 / 2 dividing ratio, which is controlled through N1 and N2 input. Grounds. Outputs dividing signal. These inputs control the selection of a dividing ratio among 1 / 1, 1 / 2, 1 / 4, and 1 / 8. FMIN terminal is selected at N1 = N2 = "L" level (1 / 1 dividing). The truth table is shown below. Connects capacitors on bias circuit. Change this pin to low to convert the IC is to stand-by mode. Remarks Built-in input Amp. provided
