Logic High Voltage must be
0.7V to 2.75V
Layout Note:
Place filters close to the power pins - 0.1uF should be closest to
the power pin. Minimize the loop path from pin to cap to power
feed via. The length of the path from the ground side of the cap
to the ground via should also be minimized.
25MHz +-5 ppm 300uW Crystal.
Reserved for EMI.
Place high-frequency decoupling caps close to the power pins. Minimize the loop path
from pin to cap to power feed via. The length of the path from the ground side of the cap to
the ground via should also be minimized.
Monitor GPHY PLL Clk
RDAC resistor R674 - 1%
- 1.15K for Docking solutions with analog s/w
- 1.24K for Non-Docking solutions
Place as close to the ASIC as possible
Place filters close to the power pins - 0.1uF should be closest to the
power pin. Minimize the loop path from pin to cap to power feed via.
The length of the path from the ground side of the cap to the ground via
should also be minimized.
Rserved for BCM5752 as
back-up solution.
Rserved for BCM5752 as
back-up solution
Rserved for BCM5752 as
back-up solution.
Layout Note:
Place termination
resistors close to LAN
controller(less than
0.25").
Reserved for BCM5752 as back-up solution.
Reserved as optional EMI filtering for BCM5755M.
LOM_CABLE_DETECT goes to an input on a
system microcontroller that can poll this signal
periodically and can de-assert the
LOM_LOW_PWR when LOM_CABLE_DETECT
signal is high. Connect to an EC GPIOC defined
by the GPIO mapping.
A2 pin:
NC for BCM5755M.
ATTN_BTTN for BCM5752.
M4 pin:
NC for BCM5755M.
SERIAL_DO/TPM_STATUS for
BCM5752.
LOM_REGSEN12 and LOM_REGSEN25 should be routed using a trace
from the load (PNP) back to the controller. Do not use a direct connection
to the power plane.Use 8 mils trace width for these signals.
33
Place R676 as close as possible to the
ASIC. Pad is needed to measure 125Mhz
clock for debugging.
