ECL
HS-2800/2810 Series
Description
The HS-2800/2810 Series of quartz crystal oscillators provide MECL 10K and 10KH series compatible
signals in industry standard four-pin DIP hermetic packages. Systems designers may now specify spacesaving, cost-effective packaged ECL oscillators to meet their timing requirements.
Features
• Wide frequency range–10.0MHz 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
• 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

Footnotes:
1) Standard frequency stability (±20,±25,±50ppm & others available)
2) VOL, VOH, referenced to ground (VCC) with VEE = -5.2V
3) Jitter performance is frequency dependent. Please contact factory for full characterization.
4) Tpd is phase shift between the falling edge of pin 8 at VCC-1.29V and rising edge of pin 1 at VCC-1.29V.
