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
