CML Microcircuits has announced their new dual VCO/PLL IC, the CMX979. Featuring wide operating frequencies combined with low power, this device is ideal for any single- or dual-heterodyne receiver in the L and S band range.
The RF Synthesizer/PLL is a fractional-N type, and covers 2.7 to 3.6 GHz. Additionally, there is a selectable frequency divider with 1/2/4/6/8 options. The total frequency range is therefore 338 MHz to 3.6 GHz. It also includes configurable current versus lock timing optimization for power-versus-performance tradeoffs.
The IF Synthesizer/PLL is an integer-N type, with a nominal frequency range of 500 to 1000 MHz. The included selectable frequency divider covers options for 1/4/8/16, providing a wide range of frequencies. Output frequencies as low as 31 MHz can be achieved.
The entire chip is housed in a 6×6 mm VQFN package, and can be controlled with a simple 3-wire serial interface.
