Order this document by MC44824/D MC44824/25 PLL Tuning Circuits with I2C Bus The MC44824/25 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 MC44824/25 are manufactured on a single silicon chip using Motorola’s high density bipolar process, MOSAIC™ (Motorola Oxide Self Aligned Implanted Circuits).

MC44824 Features

* B (signal TDI) is also initiated by any start condition on the I2C bus. At power

* on, the whole bus receiv
