HS-2820

CRYSTAL CLOCK OSCILLATORS ECL Data Sheet 0013B Rev. E HS-2820 Series Description The HS-2820 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 space-saving, 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 Electrical Connection Pin 1 7 8 14 Connection Output Complement VCC Ground Output VEE -4.5V • 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) Dimensions in inches and (MM) 357 Beloit Street, P.O.

Footnotes: 1) Standard frequency stability (±20,±25,±50ppm & others available) 2) VOL, VOH, referenced to ground (VCC) with VEE = -4.5V 3) Jitter performance is frequency dependent. Please contact factory for full characterization. RMS jitter bandwidth of 12kHz to 20MHz. 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.
