Part Number: DAC37J82
Hi
For DAC37J82, the pins SYNCBP/N are LVDS OUTPUTS. What is the meaning of Zt : internal termination 100oHm ?
I understand this point for LVDS INPUT but about LVDS OUTPUT ...? is 100ohm load ,for LVDS output , in DAC37J82 ??
Antoine,
This may be a typo in the data sheet as this makes no sense to me either. I am checking with the design team regarding this. On our EVM, we treat this as a standard LVDS output with 100 Ohm differential traces connected between these pins and the connector.
Regards,
Jim
In reply to Jim Seton:
Have you an answer from the design team to confirm about this? There is no resistor 100ohm inside the component between SYNCB+ and SYNCB-
Best regards
In reply to Antoine Michelangeli:
This is an internal termination resistance on the LVDS output. It double terminates the transmission line at the source end. The user is still required to terminate the load end of the SYNCB transmission line. See “config52” for details on the register settings. There is also control for the output current on the LVDS output in this same register.
