Description: LOW-POWER PLL TUNING CIRCUIT

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

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 10
