关于进口工控有源晶振国产化替代,以下重要电气参数值得关注:
- 温度频差Frequency Stability vs Temperature
±10ppm、±20ppm、±30ppm
- 工作温度范围Operating Temperature Range
-20~+70℃、-40~+85℃
- 输出波型Output Wave
CMOS、HCMOS、LVCMOS
- 供给电压(VDD)Recommended Operating Supply Voltage
1.8V、2.5V、2.8V、3.3V、5V±10%
- 输出负载Output Load Capacitance
15PF或30PF
注:
输出负载为15PF, 常见于工作电压为1.8V、2.5V、2.8V及3.3V的常规有源晶振。
输出负载为30PF,常见于工作电压为5V的大功率输出有源晶振。
- 消耗电流Input Current
有源晶振OSC7050/OSC5032
当VDD=3.3V时:
1.544M~32.000M :35mA(15pF)
32.000M~85.000M:45mA(15pF)
85.000M~156.250M :60mA(15pF)
当VDD=5.0V时:
1.544M~32.000M :35mA(15pF)/45mA(30pF)
32.000M~85.000M :50mA (15pF)/60mA(30pF)
85.000M~156.250M :70mA(15pF)
有源晶振OSC3225/OSC2520
1~50M: 10mA
>50M :20mA
