SC-B1420 Series LVCMOS SC-B1420 Series Rev Frequency Range: 1.0 MHz to 80.0 MHz Description The SC-B1420 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying Pin 1 of the SC-B1420 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—1.0 MHz to 80.0 MHz • 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 • No internal PLL avoids cascading PLL problems • Metal lid electrically connected to ground to reduce EMI • Gold plated pads • RoHS Compliant, Lead Free Construction Creating a Part Number SC - B142X - FREQ Package Code SC 4 pad 5x7 mm SMD 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 ppm -40 to +85°C Input Voltage Code Specification A 3.3 V B 2.5 V 5V Drawing Specifications Electrical Connection For the most up to date specifications on each NEL product, log on to our website— www.nelfc.com Dimensions shown in inches and millimeters.
