CRYSTAL CLOCK OSCILLATORS
Differential Positive ECL (DPECL)
HS-A2870 Series
Data Sheet 9544B
Rev. T
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 rangeâ15.0MHz 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)
