MCD2006G/T/R is a set of ICs for FM/FSK wireless transceiver intended for use in the VHF band, MCD2006G and MCD2006T are applied in transmitter, and MCD2006R is used in receiver. All of these three ICs contain an integrated VCO, a RF power amplifier, a reference crystal oscillator and a frequency synthesizer. A completed phase-lock-loop(PLL) is consisted by combining the ICs and on board LPF、inductor and varactors.

The difference between MCD2006G and MCD2006T/R is T/R contains a 6-bit ROM，the PLL can be locked at corresponding frequencies when users setup 6-bit ROM logic input shown in fixed logic table in appendix. The frequencies between MCD2006T and MCD2006R are corresponding each other with a455KHz frequency difference. MCD2006G contains a MCU programmable control interface which is used for setting division for any targeted frequency between3MHz~110MHz by an external MCU.

Inpractical terms MCD2006G must combine with a MCU but MCD2006T/R can be free of MCU.

Supply voltage range is 2.7 to 4.5 volts. It has been proved that MCD2006G/T/Rcan work stably between -40 to +85 degrees.
