Frequently Asked Questions
What frequency stability does ACVTX1018A-2.048MHZ-D10 provide and over which temperature range?
ACVTX1018A-2.048MHZ-D10 provides ±10 ppm frequency stability over the -10°C to +60°C operating temperature range, making it suitable for telecom line timing, GPS disciplined oscillators, and network synchronization applications where crystal oscillator drift of ±50 ppm or more would cause frame errors.
Why is 2.048 MHz specifically significant for telecommunications timing references?
2.048 MHz is the fundamental clock rate for E1 (European T1) digital trunk lines carrying 32 time slots at 64 kbit/s each, totaling 2.048 Mbit/s. ACVTX1018A-2.048MHZ-D10 provides this exact frequency at ±10 ppm accuracy, meeting ITU-T G.703 timing requirements for PDH network interface cards and telecom access equipment.
How does ACVTX1018A-2.048MHZ-D10 compare to a standard crystal oscillator at 2.048 MHz for outdoor equipment?
A standard 2.048 MHz crystal oscillator typically drifts ±50 ppm to ±100 ppm over temperature, while ACVTX1018A-2.048MHZ-D10 holds ±10 ppm from -10°C to +60°C using internal temperature compensation. For outdoor telecom nodes where ambient temperature swings 40°C, the TCXO reduces frequency error by up to 10× compared to a standard XO.
What supply voltage does ACVTX1018A-2.048MHZ-D10 require and is it compatible with 3.3 V FPGA clock inputs?
ACVTX1018A-2.048MHZ-D10 operates from a 3.3 V supply, making it directly compatible with 3.3 V LVCMOS clock inputs on FPGA, CPLD, and microcontroller devices without level-shifting. Current consumption is typically under 10 mA, enabling use in battery-powered or low-power-budget embedded timing designs.
