Decoupling of the power supplies is a critical element in maintaining the proper operation of the part. It is
recommended that the VCC power supply be decoupled using a 0.1F and 0.01F capacitor placed in parallel
on each VCC power supply pin as close to the package as possible. If room permits, a 0.001F capacitor should
also be placed in parallel with the 0.1
F and 0.01F capacitors mentioned above. Recommended capacitors are
low inductance ceramic SMT X7R devices. For the 0.1
F capacitor, a 0603 package should be used. The
0.01
F and 0.001F capacitors can be either 0603 or 0402 packages.
For low frequency decoupling, 47
F tantalum low inductance SMT caps should be sprinkled over the
board’s main +3.3V power supply and placed close to the C-L-C pi filter.
If the device is being used in an ECL environment with a -3.3V supply, then all references to decoupling
VCC must be changed to VEE, and all references to decoupling 3.3V must be changed to -3.3V.
