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 Connection Block Diagram 1 2004-08-06 TD7104FG Pin Function Pin No. Symbol 1 VCC Power supply terminal Applies voltage of VCC = 3.0 to 5.5V 2 FMIN FM local OSC. signal input terminal Inputs local oscillation signal in FM band. fIN = 50 to 200MHz, FMIN input signal is output by a 1 / 1 dividing ratio (buffer amplifier). Built−in input Amp. provided 3 TVIN TV local OSC. signal input terminal 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. Built−in input Amp. provided 4 GND Ground terminal Grounds. ― 5 Out Dividing signal output terminal Outputs dividing signal. ― 6 N1 Dividing ratio selecting control terminal 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. ― BIAS terminal Connects capacitors on bias circuit.
