ECL Prescaler for Digital Synthesized Tuner
TD7104FG
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
