| 7701 series | Since the products 7701 series has two oscillation circuits, it is possible to generate both the frequency of 32.768kHz and the frequency signal of MHz band by using only one IC. In addition, by using the above the products 7701 series , customers only need to prepare AT-cut crystal blanks, which reduce workload and costs for customers’ oscillator production. Operating temperature: -40 to 85°C |
