CRYSTAL CLOCK OSCILLATORS
Differential Positive ECL (DPECL)
Fast Edge
Data Sheet 9729A
Rev. M
HS-A2920 Series
Description
The
HS-A2920 Series
of quartz crystal oscillators provide DPECL Fast Edge compatible signals in industry
standard four-pin DIP hermetic packages. Systems designers may now specify space-saving, cost-
effective packaged PECL oscillators to meet their timing requirements.
Features
• Wide frequency range–50.0MHz to 155.520MHz
• 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
• Fast rise and fall times <600 ps
• Low Jitter
• Overtone technology
• 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)
