CRYSTAL CLOCK OSCILLATORS
Differential Positive ECL (DPECL)
HS-A2870 Series
Data Sheet 9544B
Rev. V
Description
The HS-A2870 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. This device is intended to operate on
positive voltage for PECL applications.
Features
• Wide frequency range–15.0MHz 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
• 3.3 Volt operation
• Metal lid electrically connected to ground to
reduce EMI
• Low Jitter
• MECL 10K and 10KH series compatible output on
Pin 8, 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
• RoHS Compliant, Lead Free Construction
(unless solder dipped leads are supplied)
• COTS/Dual use
