MC44827 Datasheet Low-power Pll Tuning Circuit

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: Order this document by MC44827/D Low Power PLL Tuning Circuits for 3-Wire Bus The MC44827/27B 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 MC44827 has programmable 512/1024 reference divider while the MC44827B has a fixed reference divider of 1024.

Key Features

  • as MC44817/17B but has improved sensitivity performance and reduced power dissipation. The low frequency preamplifier has been removed and the operational amplifier pull.
  • up resistor has been increased to 60 kΩ. The MC44827/27B are controlled via a 3.
  • wire bus. The MC44827/27B have the same functions as the MC44828 which is I2C bus controlled. The MC44827/27B and the MC44828 can be exchanged to allow conversion between 3.
  • wire bus and I2C bus control. The MC44827/27B are man.
