HSTL
SD-A2C00 Series
PRELIMINARY
Description
The SD-A2C00 Series of quartz crystal oscillators provide HSTL compatible signals. Systems designers
may now specify space-saving, cost-effective packaged HSTL oscillators to meet their timing requirements.
Features
· Wide frequency range50.0MHz 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 1000g
· 3.3 volt operation
· Metal lid electrically connected to ground to
reduce EMI
· Fast rise and fall times <800 ps
· High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
· Low Jitter - Wavecrest jitter characterization
available
· 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 pads

Footnotes:
1) Standard frequency stability (±20,±25,±50ppm & others available)
2) Test Load per HSTL Class I of EIA/JEDEC Standard EIA/JESD8-6.
3) Jitter performance is frequency dependent. Please contact factory for full Wavecrest characterization.
4) Tpd is phse shift between the falling edge of pin 4 and the rising edge of pin 5.
5) Open to enable pin also enables the output.
