DS15BA101: LVDS: Range 0.1V to 0.22V

Paik Jen Lee

Part Number: DS15BA101

Hi TI Team,

I required a chip that able to generate an output of LVDS signal for differential amplitude at 0.1V to 0.22V. Speed is 200MHz. May i know is there any recommend chip able to do so. As i saw all the chip minimum is only 250mV.

Thanks.

Hi Lee,

Minimum output voltage is 250mV as you noted. Please note per LVDS standard, minimum LVDS output voltage is 247mV or 250mV so these parts are compatible with LVDS standard. To achieve the voltage level you noted, you may need to use attenuator blocks and this would not be LVDS compatible.

If this is the case. What is the recommendation chip that i should use to design an output of LVDS that in the range of 0.1V to 0.22V. Since the attenuator is not the LVDS standard.

Greetings,

Please note 0.1V to 0.22V is not LVDS compatible. Please refer to the document below table 1-1 comparing LVDS versus other interfaces:

LVDS spec is typically 350mV and at minimum 247mV. 0.1V to 0.22V is not LVDS compatible. This is why we recommended attenuator to get to the levels you needed.
