Sensitive 1 GHz divide-by-64/divide-by-256 switchable prescaler
GENERAL DESCRIPTION
SAB6456 SAB6456T
The SAB6456/SAB6456T is a prescaler for UHF/VHF tuners.
It can be switched to divide-by-64 or divide-by-256 by the mode-control (MC) pin.
The circuit has an input frequency range of 70 MHz to 1 GHz, has high input sensitivity and good harmonic suppression.
