CRYSTAL CLOCK OSCILLATORS
Differential Positive ECL (DPECL)
Fast Edge
SD-A2920 Series
Data Sheet 0105C
Rev. F
Description
The SD-A2920 Series of quartz crystal oscillators provide DPECL Fast Edge compatible signals. Systems
designers may now specify space-saving, cost-effective packaged PECL oscillators to meet their timing
requirements.
Features
⢠Wide frequency rangeâ75.0MHz to 250.0MHz
(Preliminary from180+MHz to 250MHz)
⢠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 1000g
⢠3.3 volt operation
⢠Metal lid electrically connected to ground to
reduce EMI
⢠Fast rise and fall times <600 ps
