Electrical characteristics
The Differential System clock receivers core power supply voltage requirements
(O1V
DD
) are as specified in
The Differential system clock can also be single-ended. For this DIFF_SYSCLK_B
should be connected to O1V
DD
/2.
3.6.6.2
Differential System clock AC timing specifications
Differential System clock(DIFF_SYSCLK/DIFF_SYSCLK_B) input pair supports input
clock frequency of 100MHz
For AC timing specification, see
Spread Spectrum clocking is not supported on Differential System clock pair input.
3.6.7 Other input clocks
A description of the overall clocking of this device is available in the chip reference
manual in the form of a clock subsystem block diagram. For information about the input
clock requirements of functional modules sourced external of the chip, such as SerDes,
Ethernet management, eSDHC, IFC, see the specific interface section.
3.7 RESET initialization
This section describes the AC electrical specifications for the RESET initialization timing
requirements. This table describes the AC electrical specifications for the RESET
initialization timing.
