LC72134M Datasheet | SANYO

Ordering number : EN5814 CMOS IC Dual PLL Frequency Synthesizer for FM Tuner Systems Overview The LC72134M is a dual PLL frequency synthesizer product that integrates on a single chip both an AM/FM audio broadcast reception PLL circuit (main PLL) and a dedicated FM multiplex reception PLL circuit (sub PLL). Since the main PLL circuit is equivalent to the LC72135M, software developed for that product can be used with this chip. The sub-PLL circuit can be controlled independently. Functions - High-speed programmable divider - FMINa (main): 10 to 160 MHz ... Pulse swallower technique (With built-in divide-by-2 prescaler) - FMINb (sub): 10 to 160 MHz ... Pulse swallower technique...
