CRYSTAL CLOCK OSCILLATORS
Positive ECL (PECL)
HA-A870 Series
Data Sheet 9727A
Rev. L
Description
The HA-A870 Series of quartz crystal oscillators provide MECL 10K and 10KH series compatible signals in
industry standard four pin DIP hermetic package. Systems designers may now specify space-saving, cost-
effective packaged PECL oscillators to meet their timing requirements.
Features
• Wide frequency range–18.0MHz to 250.0MHz
• User specified tolerance available
• Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum
• Space-saving alternative to discrete component
oscillators
• High shock resistance, to 3000g
• 3.3Volt operation
• All metal, resistance weld, hermetically sealed
package
• Low Jitter
• MECL 10K and 10KH series compatible output on
Pin 5, complement on Pin 1
• High Q Crystal actively tuned oscillator circuit
• Power supply decoupling internal
• No internal PLL avoids cascading PLL problems
• High frequencies due to proprietary design
• Gold plated leads - Solder dipped leads available
