DS90C031: ESD Pulse on the LVDS out

James Day

Part Number: DS90C031

In the scenario of an ESD pulse coming into the LVDS output, what would that look like? Is there an I/O schematic for this or a similar part?

Hello

This part has 3kV HBM ESD in the datasheet, which means all IO pins have built-in ESD protection design. Pls refer to the apps note here for more details on ESD rating and protection.

What would the output impedance (ref to IC GND) be for this or similar LVDS outputs?

Hi James

The DS90C031 differential line driver or similar LVDS is a current mode driver which mean it has a high output impedance to maintain a constant current for a range of loads. So the output is not terminated by 100Ω for impedance matching. Pls refer to this apps note on how to terminate the device for best signal integrity.
