Said to consume 10 times less power than comparable circuits, the EM7604 CMOS crystal oscillator is intended for use with a 32.768 kHz tuning fork crystal as a low-frequency clock oscillator with no other external components required. The IC is also available as the EM1564, which combines the oscillator circuit with a tuning fork crystal in a single ceramic package. The device operates with a supply voltage ranging from 1.2V to 5.5V and with power consumption as low as 250 nA. Its on-chip oscillation capacitor provides reliable stability and a tight frequency tolerance at an extended temperature range up to 125°C. The circuit is available in a SOT23-6 package and is matched with low-cost SMD quartz available from Micro Crystal. EM MICROELECTRONIC-US INC., Colorado Springs, CO. (719) 593-2883.
