TTL CLOCK OSCILLATOR
F1100H
The F1100H Clock Oscillator is TTL compatible. It has been
designed for low current consumption and fast rise time. Its
standard 45/55% symmetry allows it to directly drive
microprocessors that previously used a divide-by-2 stage in
applications up to 50MHz. The package is all metal with pin 7 as
case ground which provides shielding to help minimize EMI
radiation.
