The Epson SG2520CAA automotive grade crystal oscillator is like the "clock heart" of intelligent automotive electronic systems, providing solid guarantees for the intelligence, safety, and comfort of automobiles with excellent performance, leading intelligent vehicles to new heights of development.

The Epson SG2520CAA crystal oscillator is a quartz crystal oscillator (SPXO) designed specifically for automotive applications. It has a small volume crystal oscillator size of 2.5x2.0mm, a four pin patch crystal oscillator, an active crystal oscillator, and a power supply voltage of 1.6V to 3.63V. It provides a wide output frequency range of 1MHz to 75MHz and can maintain stable operation in a wide temperature range of -40 ° C to 85 ° C (some models can reach 125 ° C). It has the characteristics of ultra small, lightweight, low jitter, low power consumption, low loss, and low power supply voltage. The SG2520CAA patch crystal oscillator is widely used in key fields such as ADAS, vehicle communication, and information entertainment.

Characteristics of SG2520CAA:

1. Ultra small size: 2520 package (2.5 × 2.0 × 0.8 mm), suitable for space limited automotive electronic modules such as compact cameras or central control panels.

2. Wide temperature and voltage range: Supports working temperatures from -40 ℃ to+125 ℃, with a power supply voltage of 1.6V~3.63V, covering extreme cold and hot and voltage fluctuation scenarios.

3. High stability: The frequency stability of the crystal oscillator (-40-125 ℃) is ± 100 × 10-6 (Z), which is better than that of general crystal oscillators. The crystal frequency aging rate is only ± 3x10-6/year, ensuring long-term frequency stability.

4. Low power consumption and low jitter: The CMOS output design combined with low phase noise (as low as ± 50 × 10 ⁻⁶/year) ensures the stability and energy efficiency of signal transmission. The low-power characteristics of SG2520CAA can provide stable clock signals for car audio systems without affecting the battery life of the car.

5. High speed response: Start time ≤ 5ms, rise/fall time only 3.5ns, meeting the high real-time requirements of ADAS and other scenarios.

6. Compliance: Passed AEC-Q200 automotive certification, meeting requirements for vibration resistance, impact resistance, and EMC.
