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 1 / 8, 1 / 4, or 1 / 2 dividing, which is controlled with 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. Change this pin into low, the IC is turned stand-by mode. 7 N2 8 BIAS Pin Name Function And Description Remarks Truth Table Receiving Band Input Terminal FM FMIN TV TVIN Operating Frequency Range Dividing Ratio N1 N2 50M~200MHz /1 0 0 50M~400MHz /2 1 0 100M~500MHz /4 0 1 100M~1.0GHz /8 1 1 2 2002-10-30 TD7104P/F Maximum Ratings (Ta = 25C) Characteristic Symbol Rating Unit VCC 6.5 V Power dissipation PD 450 (200) (*) mW Input voltage Vin -0.3~VCC + 0.3 V Operating temperature Topr -30~75 C Storage temperature Tstg -55~150 C Power supply voltage (*) Flat package Electrical Characteristics (unless otherwise specified, VCC = 3.0~6.0V, Ta = -30~75C) Characteristic Power supply voltage Operating supply current Stand-by current Symbol Test Circuit Test Condition Min.
