PID7v-EC603e Hardware Specifications
PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
1.8.2 PLL Power Supply Filtering
The AVdd power signal is provided on the PID7v-EC603e to provide power to the clock generation phase-
locked loop. To ensure stability of the internal clock, the power supplied to the AVdd input signal should be
ltered using a circuit similar to the one shown in Figure 13. The circuit should be placed as close as
possible to the AVdd pin to ensure it lters out as much noise as possible. The 0.1
F capacitor should be
closest to the AVdd pin, followed by the 10
F capacitor, and nally the 10 resistor to Vdd. These traces
should be kept short and direct.

1.8.3 Decoupling Recommendations
Due to the PID7v-EC603e’s dynamic power management feature, large address and data buses, and high
operating frequencies, the PID7v-EC603e can generate transient power surges and high frequency noise in
its power supply, especially while driving large capacitive loads. This noise must be prevented from
reaching other components in the PID7v-EC603e system, and the PID7v-EC603e itself requires a clean,
tightly regulated source of power. Therefore, it is recommended that the system designer place at least one
decoupling capacitor at each Vdd and OVdd pin of the PID7v-EC603e. It is also recommended that these
decoupling capacitors receive their power from separate Vdd, OVdd, and GND power planes in the PCB,
utilizing short traces to minimize inductance.
These capacitors should vary in value from 220 pF to 10
F to provide both high- and low-frequency
ltering, and should be placed as close as possible to their associated Vdd or OVdd pin. Suggested values
for the Vdd pins—220 pF (ceramic), 0.01
F (ceramic), and 0.1 F (ceramic). Suggested values for the
OVdd pins—0.01
F (ceramic), 0.1 F (ceramic), and 10 F (tantalum). Only SMT (surface mount
technology) capacitors should be used to minimize lead inductance.
In addition, it is recommended that there be several bulk storage capacitors distributed around the PCB,
feeding the Vdd and OVdd planes, to enable quick recharging of the smaller chip capacitors. These bulk
capacitors should also have a low ESR (equivalent series resistance) rating to ensure the quick response time
necessary. They should also be connected to the power and ground planes through two vias to minimize
inductance. Suggested bulk capacitors—100
F (AVX TPS tantalum) or 330 F (AVX TPS tantalum).
1.8.4 Connection Recommendations
To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal
level. Unused active low inputs should be tied to Vdd. Unused active high inputs should be connected to
GND. All NC (no-connect) signals must remain unconnected.
Power and ground connections must be made to all external Vdd, OVdd, and GND pins of the PID7v-
EC603e.
