AKM releases fractional-N PLL synthesizer

Asahi Kasei Microdevices Corporation (AKM) has launched a fractional-N PLL IC, the AK1574, the company said.

A built-in VCO saves space, has low-phase noise, and low-power consumption. Uses include two-way radios in the VCO configuration with a variable capacitance diode and a winding coil. This product is targeting professional, portable radio equipment.

The AK1574 is optimized for narrow band radio below 1GHz. While achieving low normalized phase noise of -221dBc/Hz, it operates with power consumption of 90mW, (3V/single output), at -6dBm output.

Asahi Kasei Microdevices is a Japan-based company, designs and manufactures CMOS mixed signal integrated circuits and magnetic sensors for applications including audio, multimedia, consumer electronics, industrial infrastructure, and telecommunications. AKM has continued to provide customers with optimum solutions all over the world for over 30 years.
