REFCLK&RST CIRCUITS, PCIE P1
PEX8647RDK
PCIE MALE CONNECTOR P1
R6-R9 SHOUD BE CLOSE TO PIN 6& 7 OF U2
REFCLK CIRCUIT
R10-R13 SHOUD BE CLOSE TO PIN9 & 10 OF U2
R14-R17 SHOUD BE CLOSE TO PIN19 & 20 OF U2
R18-R21 SHOUD BE CLOSE TO PIN22 & 23 OF U2
Pin 1&2 of J1 should be routed
on refclk traces of SLOT1
without any stubs
RESET CIRCUIT
C122 IS USED TO SET THE RESET TIMEOUT
PERIOD FOR U4. A VALUE OF 0.001UF RESULTS
IS APPROXIMATELY 3MS.
Impedance Test Traces
ITP1-ITP16 are probe holes for impendance
test. They should be 25mils in diameter
Ground Posts
The hole size of GP1-4 should be
same as the jumper header
