LC7153M
LC7153M is Universal Dual-PLL Frequency Synthesizers manufactured by SANYO.
Overview
The LC7153 and LC7153M are universal dual-PLL frequency synthesizers for use in cordless telephone applications in the USA, South Korea and Australia, and satellite broadcast tuners in the USA and Europe. The LC7153 and LC7153M both have two PLLs with a 16-bit programmable divider to generate a 1.5 to 160MHz local-oscillator frequency, and a phase detector. They also have a dual charge pump and fast lock-up circuitry for rapid PLL locking when changing frequency, an unlock indication output and an unmitted output under external control. The PLLs share a 14-bit divider to generate a 320Hz to 640k Hz reference frequency using a 10.24MHz crystal. The LC7153 and LC7153M can be controlled from an external microcontroller using a C2B serial interface. They also have a standby mode for single PLL operation. The LC7153 and LC7153M operate from a 4.0 to 5.5V supply. The LC7153 is available in 24-pin DIPs, and the
LC7153M, in 24-pin MFPs.
