NEL SH-A1480-FREQ

CRYSTAL CLOCK OSCILLATORS
LVCMOS
Data Sheet 0514E
Rev. A
SH-B1480 Series
Description
The SH-B1480 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible
signals for bus connected systems. Supplying Pin 1 of the SH-B1480 units with a logic “1" or open enables
its Pin 4 output. In the disable mode, Pin 4 presents a high impedance to the load.
Features
• Wide frequency range–150.0MHz to 280.0MHz
(Contact factory for other frequencies)
• User specified tolerance available
• Will withstand SMD reflow temperatures of 253°C
for 4 minutes maximum
• Space-saving alternative to discrete component
oscillators
• 2.5 Volt operation
• High shock resistance, to 1000g
• Low Jitter - Wavecrest jitter characterization
available
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• High Q Crystal actively tuned oscillator circuit
• Power supply decoupling internal
• No internal PLL avoids cascading PLL problems
• High frequencies due to proprietary design
• Metal lid electrically connected to ground to
reduce EMI
• Gold plated pads
• RoHS Compliant, Lead Free Construction
