Part Number: TS5A3159A
Other Parts Discussed in Thread: SN74LVC1G3157

Hi team,

customer has a 3.3V 4MHz and a 1.8V 37.125MHz clock signal need to switch. I was wondering if TS5A3159A can work here. If not, any recommended device for it?

This switch has a specified bandwidth of 100 MHz. Use something like the SN74LVC1G3157.

Hello Rayna,

I would recommend the SN74LVC1G3157 It can support up to 300MHz and the customer trying to send a clock signal of 37MHz. A good estimation is 5x the frequency of the application. For this use case 37 x 5 = 185MHz, which the SN74LVC1G3157 can support.
