Pin Descriptions (ICS552-01—C mode)
External Components
Series Termination Resistor
Clock output traces over one inch should use series
termination. To series terminate a 50
trace (a
commonly used trace impedance), place a 33
resistor
in series with the clock line, as close to the clock output
pin as possible. The nominal impedance of the clock
output is 20
.
Decoupling Capacitors
As with any high-performance mixed-signal IC, the
ICS552-01 must be isolated from system power supply
noise to perform optimally.
Decoupling capacitors of 0.01F must be connected
between each VDD and GND on pins 4 and 6, and 16
and 14. Other VDDs and GNDs can be connected to
these pins or directly to their respective ground planes.
Crystal Load Capacitors
The device crystal connections should include pads for
small capacitors from X1 to ground and from X2 to
ground. These capacitors are used to adjust the stray
capacitance of the board to match the nominally
required crystal load capacitance. Because load
capacitance can only be increased in this trimming
process, it is important to keep stray capacitance to a
minimum by using very short PCB traces (and no vias)
been the crystal and device. Crystal capacitors must be
connected from each of the pins X1 and X2 to ground.
The value (in pF) of these crystal caps should equal
(CL -12 pF)*2. In this equation, CL= crystal load
capacitance in pF. Example: For a crystal with a 18 pF
load capacitance, two 12 pF capacitors should be
used. For a clock input, connect it X1/ICLK and leave
X2 unconnected (floating).
