ECL Prescaler For Digital Synthesized Tuner

TD7104P,TD7104F are general−purpose fixed dividing prescaler developed for digital tuning system of PLL frequency synthesizer type, and can operate up to 1GHz.

Features

• Maximum operating frequency 1GHz. (at 1 / 8 dividign mode)

• Dividing ratios of 1 / 8, 1 / 4, and 1 / 2 are provided.

• 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 stand−by circuit
