32768-Slide2

This slide shows the outlook for Kyocera’s 32.768kHz solution. The left side of the table shows ST3215SB, a simple Tuning Fork Crystal. There are three different clock oscillators in the middle of the table, and Digital TCXO and the Real Time Clock Module on the right. Tuning Fork Crystals have rough temperature characteristics, -350 to 0 ppm over -40 to 125°C. The further right that the product goes, the tighter the temperature characteristic will be, up to +/- 5 ppm over -40 to +85°C. On the other hand, the current consumption of each device is significantly lower.
