Applications Information
Crystal Selection
The DS1080CL requires a parallel resonating crystal
operating in the fundamental mode, with an ESR of less
than 90
Ω. The crystal should be placed very close to
the device to minimize excessive loading due to para-
sitic capacitances.
Oscillator Input
When driving the DS1080CL using an external oscillator
clock, consider the input (X1) to be high impedance.
Crystal Capacitor Selection
The load capacitors CL1 and CL2 are selected based
on the crystal specifications (from the data sheet of the
crystal used). The crystal parallel load capacitance is
calculated as follows:
For the DS1080CL use CL1 = CL2 = CLX.
In this case, the equation then reduces to:
where CL1 = CL2 = CLX.
Equation 2 is used to calculate the values of CL1 and
CL2 based on values of CL and CIN noted in the electri-
cal specifications.
Power-Supply Decoupling
To achieve best results, it is highly recommended that
a decoupling capacitor is used on the IC power-supply
pins. Typical values of decoupling capacitors are
0.001μF and 0.1μF. Use a high-quality, ceramic, sur-
face-mount capacitor, and mount it as close as possi-
ble to the VCC and GND pins of the IC to minimize lead
inductance.
Layout Considerations
As noted earlier, the crystal should be placed very
close to the device to minimize excessive loading due
to parasitic capacitances. Care should also be taken to
minimize loading on pins that could be open as a pro-
gramming option (SMSEL and CMSEL). Coupling on
inputs due to clocks should be minimized.
