Pin Assignment
Pin Descriptions
External Component Selection
The ICS726A requires a minimum number of external
components for proper operation.
Decoupling Capacitor
A decoupling capacitor of 0.01F must be connected
between VDD (pin 4) and GND (pin 2), as close to these
pins as possible. For optimum device performance, the
decoupling capacitor should be mounted on the component
side of the PCB. Avoid the use of vias in the decoupling
circuit.
Series Termination Resistor
When the PCB trace between the clock output (CLK, pin 3)
and the load is over 1 inch, series termination should be
used. To series terminate a 50
Ω trace (a commonly used
trace impedance) place a 33
Ω 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
Ω.
Quartz Crystal
The ICS726A VCXO function consists of the external crystal
and the integrated VCXO oscillator circuit. To assure the
best system performance (frequency pull range) and
reliability, a crystal device with the recommended
parameters (shown below) must be used, and the layout
guidelines discussed in the following section shown must be
followed.
The frequency of oscillation of a quartz crystal is determined
by its “cut” and by the load capacitors connected to it. The
ICS726A incorporates on-chip variable load capacitors that
“pull” (change) the frequency of the crystal. The crystal
specified for use with the ICS726A is designed to have zero
frequency error when the total of on-chip + stray
capacitance is 8.9 pF.
