CRYSTAL CLOCK OSCILLATORS
Description
The HS-1430 Series of quartz crystal
oscillators provide enable/disable 3-state
CMOS compatible signals for bus connected
systems. Supplying Pin 1 of the HS-1430
units with a logic “1” or open enables its Pin “8”
output. In the disable mode, Pin “8” presents a
high impedance to the load.

Suggested Applications
The HS-1430 Series oscillators are
ideally suited for applications involving
more than one clock or source on the same
bus. The high impedance state allows ATE
(Automatic Test Equipment) board testing
without having to remove the oscillator. In
multiplexing applications, multiplex clock
signals can be made available to a system
using the enable/disable 3-state feature.
Features
• Wide frequency range—68.0MHz to 145.0MHz
• User specified tolerance from ±20ppm
• Case at electrical ground
• Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum
• All metal, resistance weld, hermetically sealed package
• High shock resistance, to 3000g

Specialty Oscillators for Unique Requirements
If the characteristics listed above do not meet your specific
requirements, specialty solutions are often available.
For example, if you need better stability, extended
temperature range, or tighter symmetry, NEL can provide
a HS-1439 series oscillator to serve your needs.
To let us know your special requirements, complete our
Specialty Oscillator sheet. We will respond with the desired
specialty oscillator, or discuss with you a solution that most
closely meets your needs.
This information has been carefully prepared and is believed to be entirely
reliable. However, no responsibility is assumed for inaccuracies. NEL reserves
the right to make changes at any time in order to improve design and supply
the best product possible.
