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
• 6-Pin SMD package
Applications
• Base stations
• Fast warm-up
• Test equipment
• Small Cells
• Military communication equipment
• Packet based timing (e.g. 1588).
• 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.
