MC44817 Datasheet Tv And Vcr Pll Tuning Circuits

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: Order this document by MC44817/D MC44817/17B PLL Tuning Circuits with 3-Wire Bus The MC44817/17B are tuning circuits for TV and VCR tuner applications. They contain on one chip all the functions required for PLL control of a VCO. The integrated circuits also contain a high frequency prescaler and thus can handle frequencies up to 1.3 GHz. The MC44817 has programmable 512/1024 reference divider while the MC44817B has a fixed reference divider of 1024. The MC44817/17B are manufactured on a single silicon chip using Motorola’s high density bipolar process, MOSAIC™ (Motorola Oxide Self Aligned Implanted Circuits). TV AND VCR PLL TUNING CIRCUITS WITH 1.3 GHz PRESCALER AND 3–WIRE BUS SEMICONDUCTOR TECHNICAL DATA • • • • • • • • • • • • • plete Single Chip System for MPU Control (3–Wire Bus).
