marginal working conditions. Recommended component
values for various IC’s and microprocessors are given in
theAppendix “Application Circuits for Ceramic Resona-
tors.” These values should be checked in the actual oper-
ating circuit to confirm their performance over changing
conditions of input voltage and temperature.
