Hi all,
In the schematic of an evaluation board I've seen some clock nets like that:
parallel term to gnd R=178 ohm
|
|
|---SERIES TERM 36ohm----Tline 55
ohm------|----RECEIVER
DRIVER 7 ohm--------|
| --SERIES TERM 36ohm-----Tline 55
ohm------|---RECEIVER
|
|
parallel term to gnd R=178 ohm
Can someone explain me why the value of the parallel term is 178 ohm?
Any comment will be appreciate.
Thanks in advance
Lucas
