OX-503 Oven Controlled Crystal Oscillator OX-503 Description OX-503 is a small form factor precision OCXO providing SC cut levels of reliability, aging and noise performance in a tiny footprint, making the OX-503 ideal for designs where high performance is required but space is limited. Features Applications • 6-Pin SMD package • Fast warm-up • TCXO replacement for better short term stability • Frequency Range, 10 MHz to 52 MHz • SC-Cut Design • Standard freq.: 10; 19.44; 20; 24.576; 25; 30.72; 38.88; 40; 50;51.2 MHz. • Base stations • Test equipment • Small Cells • Military communication equipment • Packet based timing (e.g. 1588).
