TI中文支持网Part Number:ADC3660EVMOther Parts Discussed in Thread:ADC3662EVM, ADC3664EVM, ADC3683EVM, , ADC3660
According to the user guide of ADC3662EVM, ADC3663EVM, ADC3664EVM, ADC3683EVM, there is a glitch filter before the ADC in the EVMs. However, there is no glitch filter in the ADC3660EVM. I have the following questions:
(1) Is there a glitch filter before the ADC (ADC3660) in the ADC3660EVM?
(2) Will the glitch filter affect the analog input bandwidth of the ADCs (900 MHz)?

您好，
1、ADC3660EVM中有glitch filter，ADC3660EVM产品主页中没有提供其原理图，我在下面E2E帖子中找到了其EVM原理图，原理图中可以看到其具有 DC to 30 MHz的glitch filter ：

或直接查看原理图： ADC3660EVM schematic
2、ADC3660 datasheet中给出了两种glitch filter，可以看出glitch filter对输入信号频率是有影响的，因此不同的输入频率范围应使用不同的滤波器设计
