AC Electrical Characteristics
VDD = 3.3 V ±5%, Ambient Temperature -40 to +85
°C, C
LOAD at CLK = 15 pF, unless stated otherwise.
VDD = 5.0 V ±10%, Ambient Temperature -40 to +85
°C, C
LOAD at CLK = 15 pF, unless stated otherwise.
Note 1: Minimum input frequency is limited by loop filter design. 1 kHz is a practical minimum limit.
External Components
The ICS673-01 requires a minimum number of external
components for proper operation. A decoupling capacitor of
0.01
F should be connected between VDD and GND as
close to the ICS673-01 as possible. A series termination
resistor of 33
may be used at the clock output.
Special considerations must be made in choosing loop
components CS and CP. These can be found online at
http://www.icst.com/products/telecom/loopfiltercap.htm
Avoiding PLL Lockup
In some applications, the ICS673-01 can “lock up” at the
maximum VCO frequency. This is usually caused by power
supply glitches or a very slow power supply ramp. This
situation also occurs if the external divider starts to fail at
high input frequencies. The usual failure mode of a divider
circuit is that the output of the divider begins to miss clock
edges. The phase detector interprets this as a too low
output frequency and increases the VCO frequency. The
