Description
The HA-2870 Seriesof 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
• 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 upon request
