DD

 pin on the MSC8101 should be provided with a low-impedance path to the board’s 

power supply. Similarly, each 

GND

 pin should be provided with a low-impedance path to ground. The 

power supply pins drive distinct groups of logic on the chip. The 

V

CC

 power supply should be bypassed 

to ground using at least four 0.1 µF by-pass capacitors located as closely as possible to the four sides of 
the package. The capacitor leads and associated printed circuit traces connecting to chip 

V

CC

, 

V

DD

, and 

GND

 should be kept to less than half an inch per capacitor lead. A four-layer board is recommended, 

employing two inner layers as 

V

CC

 and 

GND

 planes. 

All output pins on the MSC8101 have fast rise and fall times. Printed circuit board (PCB) trace 
interconnection length should be minimized in order to minimize undershoot and reflections caused by 
these fast output switching times. This recommendation particularly applies to the address and data 
busses. Maximum PCB trace lengths of six inches are recommended. Capacitance calculations should 
consider all device loads as well as parasitic capacitances due to the PCB traces. Attention to proper PCB 
layout and bypassing becomes especially critical in systems with higher capacitive loads because these 
loads create higher transient currents in the 

V

CC

, 

V

DD

, and 

GND

 circuits. Pull up all unused inputs or 

signals that will be inputs during reset. Special care should be taken to minimize the noise levels on the 
PLL supply pins.

There are 2 pairs of PLL supply pins: 

V

CCSYN

SYN

 and 

V

CCSYN1

. Each pair supplies one

V

V

CCSYN1

 inputs with a circuit 

similar to the one in Figure 4-2.. To filter as much noise as possible, place the circuit as close as possible 
to 

V

CCSYN

 and 

V

the 10-µF capacitor, the 10-nH inductor, and finally the 10-

short and direct.

, respectively, by a 0.01-µF capacitor located as close as possible to
