Description

The SC14431A2NF MDCX is an electronic component model categorized as an IC chip. It belongs to the SC-B1440 Series of quartz crystal oscillators, which provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. When Pin 1 is supplied with a logic "1" or left open, Pin 3 is enabled and presents an output. In the disable mode, Pin 3 offers a high impedance to the load.

Specifications and features

The SC14431A2NF MDCX offers the following specifications and features:

• Wide frequency range of 80.0MHz to 125.0MHz (Contact factory for other frequencies)
• User specified tolerance available
• Can withstand vapor phase temperatures of 253°C for a maximum of 4 minutes
• Space-saving alternative to discrete component oscillators
• Operates at 2.5 Volts
• High shock resistance, up 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

Application Scenarios

The SC14431A2NF MDCX can be used in various electronic systems that require quartz crystal oscillators with enable/disable functionality, such as bus connected systems where Pin 3 output needs to be controlled.
