EB19E2 Crystal Clock Oscillators Ecliptek EB19E2 Crystal Clock Oscillators are quartz crystal low voltage ceramic metal oxide semiconductor (LVCMOS) type oscillators with a 1MHz to 50MHz nominal frequency range. These clock oscillators feature a maximum 15pF load drive capability and consist of a Tri-State (high impedance) pin connection. The EB19E2 oscillators support ±25ppm frequency tolerance at the -40°C to +85°C temperature range and maintain high stability over operating temperature, supply voltage, and output voltage changes. These crystal oscillators offer a small start-up time, low input current, and very small rise/fall time.
