PLL-Filter
The pin PLLOUT should be connected as shown below:
R1 = 249_ ± 5%,
W
C1 = 1nF, ± 5%, 200V
C2 = 15nF, ± 5%, 200V
Power and Ground Guidelines
To achieve its fast cycle time, the T7906E is designed with high speed drivers on output
pins. Large peak currents may pass through a circuit board
’
s ground and power lines,
especially when many output drivers are simultaneously charging or discharging their
load capacitances. These transient currents can cause disturbances on the power and
ground lines. To minimize these effects, the T7906E provides separate supply pins for
its internal logic and for its external drivers.
All GND pins should have a low impedance path to ground. A ground plane is required
in T7906E systems to reduce this impedance, minimizing noise.
The VCC pins should be bypassed to the ground plane using 8 high-frequency capaci-
tors (0.1 mF ceramic). Keep each capacitor
’
s lead and trace length to the pins as short
as possible. This low inductive path provides the T7906E with the peak currents
required when its output drivers switch. The capacitors
’
ground leads should also be
short and connect directly to the ground plane. This provides a low impedance return
path for the load capacitance of the T7906E output drivers.
The following pins must have a capacitor: 1, 4, 16, 27, 56, 61, 88 and 99.
