DS250DF810: 85 ohm differential impedance

Art Mecina

Part Number: DS250DF810

Hello Guys,

Good day.

Can the DS250DF810ABVT be used with 85 ohm differential impedance? If not, does TI offer a protocol-independent retimer for rates up to 10.3125Gbps @ 85 Ohm differential?

Thanks and regards,

Hello Art,

For all TI retimers, a 100 ohm +/-10% differential impedance is recommended. A 85 ohm termination is far off the required impedance and this would affect return loss and thus signal integrity.
