IQD launch a new range of clock oscillator IQXO-984, IQXO-985, IQXO-986 for use in hand held and battery powered operations
IQD have launched what they believe to be the world’s smallest 32.768kHz clock oscillator in a design that also delivers very low power. Measuring just 1.6 x 1.2 x 0.7mm, the new model is housed in a hermetically sealed ceramic package.
With a current consumption of only 30µA and with a standby current as low as 3µA, this ultra-low power clock oscillator is ideal for use in hand held and battery powered applications and where accuracy is required in real time clocks. Typical applications include battery management systems, communication modules and systems (Bluetooth, Wi-Fi, Wireless LAN & Zigbee), LCD lighting systems and smart meters (AMR).
The new range delivers better temperature characteristic than standard 32.768kHz tuning fork crystal based oscillators due to the use of an AT-cut crystal normally found in higher frequency oscillators. Start-up time is only 7ms at 3.3V with a rise and fall time of 200ns.
These CMOS based oscillators are available in three supply voltages: 1.8V (IQXO-986), 2.5V ( IQXO-985) and 3.3V (IQXO-984) with frequency stabilities of ±30ppm over an operating temperature range of -20 to 70 degrees C or ±50ppm over -40 to 85 degrees C.
