SH-B1480

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 Electrical Connection Pin 1 2 3 4 5 6 Connection Enable/Disable NC Ground Output NC VDD • 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 357 Beloit Street, P.O.
