HIGH SPECIFICATION OSCILLATORS
EQLXO-2000 SERIES
8 pin Dual-in-Line
MIL SPECIFICATION OSCILLATORS
DESCRIPTION
Euroquartz EQLXO-2000 series 8 pin DIL oscillators are designed for
military, aerospace and similar applications requiring high reliability
components. Material specification consists of a hybrid circuit substrate
with all-ceramic components coupled with a ruggedized crystal mounting
system. This design specification ensures that EQLXO-2000 series
oscillators provide a highly reliable and accurate source of clock signals,
in a package able to withstand severe environmental conditions.

POWER DOWN vs TRISTATE
Power Down:
Tristate:
When Pin 1is low (0) the oscillator stops oscillation.
When Pin 1 is low the oscillator is running. However,
the output buffer amplifier stops functioning and the
Pin 5 output is in high impedance state.
