Power and Ground Signal Inputs
Power Name
Description
VDD
Internal Logic Power
VDD dedicated for use with the device core. The voltage should be well-regulated and the input should be provided with
an extremely low impedance path to the VDD power rail.
VDDH
Input/Output Power
This source supplies power for the I/O buffers. The user must provide adequate external decoupling capacitors.
VCCSYN
System PLL Power
VCC dedicated for use with the system Phase Lock Loop (PLL). The voltage should be well-regulated and the input
should be provided with an extremely low impedance path to the VCC power rail.
VCCSYN1
SC140 PLL Power
VCC dedicated for use with the SC140 core PLL. The voltage should be well-regulated and the input should be provided
with an extremely low impedance path to the VCC power rail.
GND
System Ground
An isolated ground for the internal processing logic. This connection must be tied externally to all chip ground
connections, except GNDSYN and GNDSYN1. The user must provide adequate external decoupling capacitors.
GNDSYN
System PLL Ground
Ground dedicated for system PLL use. The connection should be provided with an extremely low-impedance path to
ground.
GNDSYN1
SC140 PLL Ground 1
Ground dedicated for SC140 core PLL use. The connection should be provided with an extremely low-impedance path
to ground.
