Other Parts Discussed in Thread: SN65LVDS34, DS90LV011A

My customer have following requirements -

Have a requirement of ultra low jitter, clock(1Ghz) buffer with -

1. One single ended NIM(fast-negative logic) input to two differential LVDS &

2. One single ended 3.3V LVTTL input to two differential LVDS device.

Could you please help recommend suitable part?

Hello Supeda,

I don't think we have something that will take NIM signal directly. I will look more into it and get back to you. Do you know the specific jitter requirement?

Hi Yaser,

The jitter requirement is less than 20ps. I think Negative ECL with configurable offset will support NIM signal. Do you have any device for NECL input?

Hi Prasanta,

Please check out SN65LVDS34 which has a wide input common mode from -4 to 5V: www.ti.com/.../sn65lvds34 .
Also check out this app note that discusses how to use it to receive NECL input: www.ti.com/.../slla101 .

For single ended LVTTL to LVDS, please check out DS90LV011A.

Yaser
