3754 1.6 SL1461 WIDEBAND PLL FM DEMODULATOR The SL1461 is a wideband PLL FM demodulator, intended primarily for application in satellite tuners.

The device contains all elements necessary, with the exception of external oscillator sustaining network and loop feedback components, to form a complete PLL system operating at frequencies up to 800MHz.

An AFC with window adjust is provided, whose output signal can be used to correct fo
