Reset Circuit
Two reset circuits are provided, each with a
TPS3705-33
processor supervisory circuit, which ensures
that the reset is only released once the 3.3V power supply is within its normal limits, and that the reset
pulse period has a well-defined period.
Additionally, the Reset signal for the
GR716
(
RST_GR716_N
) can be reset by the Backplane, or the
Front Panel reset button.
The Reset signal for the
FPGA(SOC)
and
Ethernet PHY’s
(
RST_SOC_N
) is derived from
RST_GR716_N,
but can additionally be reset by the Watchdog (
WDOGN
) output of the GR716.
