MC12147 Datasheet (Motorola) - LOW POWER VOLTAGE CONTROLLED OSCILLATOR BUFFER

MC12147, LOW POWER VOLTAGE CONTROLLED OSCILLATOR BUFFER

Order this document by MC12147/D Low Power Voltage Controlled Oscillator Buffer The MC12147 is intended for applications requiring high frequency signal generation up to 1300 MHz.

An external tank circuit is used to determine the desired frequency of operation.

The VCO is realized using an emitter coupled pair topology.

The MC12147 can be used with an integrated PLL IC such as the MC12202 1.1 GHz Frequency Synthesizer to realize a complete PLL sub system.

The device is specified

MC12147 Features

* citance effects of the varactor which controls the tank resonant frequency and tuning range. Now the results calculated from Equation 2, Equation 3 and Equation 4 can be substituted into Equation 1 to calculate the actual frequency of the tank. To aid in analysis,
