LC7153中文资料三洋数据手册PDF规格书

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.

Features

• Dual charge pump and fast lock-up circuitry for rapid PLL locking.

• PLL unlock indication.

• 16-bit programmable local-oscillator divider.

• 1.5 to 160MHz local-oscillator frequency (VDD=4.0 to 5.5V).

• 14-bit programmable reference-frequency divider.

• 320Hz to 640kHz reference frequency using a 10.24MHz crystal.

• LPF transistor.

• C2B serial interface.

• 4.0 to 5.5V supply.

• 24-pin DIP (LC7153) and 24-pin MFP (LC7153M)
