Features
Description
Applications
The TX-801 TCXO provides a temperature stability of ±100ppb in a 5x3.2mm package and is fully compliant with Stratum 3
requirements. It is ideal for timing over IP applications such as 1588 PTP and Synchronous Ethernet.
Features
• Excellent temperature stability, Stratum 3 compliant
• CMOS and clipped sinewave output
• Low phase noise
• Small size, low profile
• 100% RoHS compliant
• Frequency range: 8 - 26 MHz
• Standard frequencies: 9.6, 10, 12.8, 13, 19.2, 20, 26MHz
• Up to 52MHz on request for reduced stabilities
Applications
• 1588 applications
• Wireline Stratum 3 applications
• Test & Measurement
• Wireless Communications
• Small Cells
