electronica 2012: IQD unveils low power clock oscillator

IQD's new CFPS-115 crystal clock oscillator is designed to offer low phase noise and low current consumption.

At 40.0MHz, the phase noise performance is rated at around -80dBc/Hz at 10Hz offset and 145dBc/Hz at 1kHz offset, figures which the company claims are around 5dBc better than similar design parts. The model's power consumption is rated at 7mA and is available at any frequency between 26 and 44MHz. Operating from a standard 3.3V source, the device also has tri-state capability which enables the unit to be isolated in circuit for operations such as in-circuit fault finding. The CFPS-115 is housed in a 2.5 x 2 x 0.8mm hermetically sealed ceramic package incorporating a metal lid, the use of which is said to aid in the reduction of EMI radiation. Operating over a temperature range of -40 to 85°C, the device can be specified down to a stability of ±30ppm.
