SC-B1440

www.DataSheet4U.com SC-B1440 Series LVCMOS SC-B1440 Series Rev J Frequency Range: 70.0 MHz to 220.0 MHz Description The SC-B1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying Pin 1 of the SC-B1440 units with a logic “1” or open enables its Pin 3 output. In the disable mode, Pin 3 presents a high impedance to the load. Features Size, mm 5x7 I/O 4 pad Supply Voltage 3.3V / 2.5V / 5V High Reliability - NEL HALT/HASS qualified for crystal oscillator start-up conditions Low jitter - Wavecrest jitter characterization available Wide frequency range—70.0 MHz to 220.0 MHz (Contact factory for other frequencies) User specified tolerance available Will withstand vapor phase temperatures of 253°C for 4 minutes maximum Space-saving alternative to discrete component oscillators 2.5 Volt operation High shock resistance, to 1000g 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 Creating a Part Number SC - B144X - FREQ Package Code SC 4 pad 5x7 mm SMD Input Voltage Code Specification A 3.3 V B 2.5 V 5V Tolerance/Performance 0 ±100 ppm 0-70°C 1 ±50 ppm 0-70°C 7 ±25 ppm 0-70°C 9 Customer Specific A ±20 ppm 0-70°C B ±50 ppm -40 to +85°C C ±100...
