Available in frequencies ranging from 1 to 125 MHz, the EPO series of programmable clock oscillators have an optional three-state or power-down function, ±50 or ±100 ppm frequency stability, and CMOS or TTL output duty cycle. The EP1100 and EP2500 are 5V versions and the EP1300 and EP2600 are 3.3V types. The oscillators come in 14-pin or 8-pin hermetically sealed DIPs or ceramic or plastic SMT packages; and by employing a proprietary design and programming method, the parts can be shipped in as little as three days.
