The following are several recommended crystal oscillator models and procurement codes from Epson's component agent, Piezoman, for automotive intelligent driving devices.

1. We recommend SG-3031CMA 32.768000 kHz B for active crystal oscillator, with procurement code X1B000401A001. This 32.768kHz active crystal oscillator can be easily matched and tested, making it more convenient to use. The SG-3031CMA and Epson's renowned FC-135 32.768kHz crystal resonator have exactly the same size of 3225. Its use of CMOS IC can reduce current consumption, and the power supply voltage supports a minimum of 1.2V, meeting the new trend of low voltage and low power consumption,. The frequency tolerance of SG-3031CMA is 5 ± 23/+25 ℃, and it can stably output accurate clock signals within the range of -40 ℃~105 ℃, fully capable of working in relatively harsh working conditions of automobiles. Can be used in engine control units (ECUs) and clocks with counting and sleep functions.

2. We recommend the SG-8101CGA 50.000000 MHz TJJSA, with a procurement code (PN) of X1G0051710139, as another temperature compensated crystal oscillator. This is a high-precision and highly stable programmable crystal oscillator with a frequency of 50MHz, supporting working voltages of 1.6~3.6V. In addition to stable and reliable electrical performance, the biggest advantage of the SG-8101CGA series is its fast delivery capability. Whether it is the development stage or mass production stage of intelligent driving products, samples and bulk supply can be quickly obtained.

3. We recommend the Epson FA2016AA series for passive crystal oscillators. This 2016 small-sized crystal resonator is a mature mass-produced model of Epson. We recommend using FA2016AA 24MHz (X1E000381A014 or X1E000381A091)/25MHz (X1E000381A131 or X1E000381A15500)/32MHz (X1E000381A055)/40MHz (X1E000381A101 or X1E000381A11600) and 50MHz (X1E000381A104), which are commonly used standard frequencies (and part numbers). Load capacitors can be selected from 8pF and 10pF. Choosing models that most manufacturers purchase will actually result in faster sample and bulk delivery.
