## Connection.
|
|
|
|
|
|
Mini-WR provides the following connections:
|
|
|
|
|
|
*Castellated edge contact**
|
|
|
|
|
|
2 pairs of differential GTP pairs are linked to the Castellated edge
|
|
|
contact. SI can be fulfilled by solder the Mini-WR to the carrier board.
|
|
|
Special PCB cut-out should be implemented on the carrier board due to
|
|
|
the R/C on the bottom of the Mini-WR.
|
|
|
RMII signal group, UART, SFP control signals and few debug IO are also
|
|
|
available.
|
|
|
|
|
|
*Mezzostak connector**
|
|
|
|
|
|
Another 2 Pairs of GTP differential signals are linked to the Mezzostak
|
|
|
connector, and flyby further to the gold-finger connector.
|
|
|
|
|
|
When use the Mezzostak connector, the additional trace to the
|
|
|
gold-finger acts as branch. Although our test shows that the signal can
|
|
|
suffer the small branch, it is still recommended to remove gold-finger
|
|
|
zone when the Mezzostak connector is used (need to contact the
|
|
|
producer).
|
|
|
|
|
|
The 60Pos. Mezzostak connector also provides signals for RMII, UART and
|
|
|
JTAG.
|
|
|
|
|
|
*Gold-finger connector**
|
|
|
|
|
|
The signals connected to 40Pos. Gold-finger are subset of those on the
|
|
|
Mezzostak connector, without JTAG, UART and few data signals of the
|
|
|
RMII. The Mezzostak is in the trace path and cause no interference.
|
|
|
|
|
|
When use the gold-finger, 3 types of MEC1 series connector can be
|
|
|
used.
