Frequency Rejection Selection (CA0/F0)
The LTC2483 internal oscillator provides better than 87dB
normal mode rejection at line frequencies of 50Hz and
60Hz and all of their harmonics (up to the 255th) from
48Hz to 62.4Hz.
When a fundamental rejection frequency different from
50Hz/60Hz is required or when the converter must be
synchronized with an outside source, the LTC2483 can
operate with an external conversion clock. The converter
applicaTions inFormaTion
automatically detects the presence of an external clock
signal at the CA0/F0 pin and turns off the internal oscilla-
tor. The chip address for CA0 is internally set HIGH. The
frequency fEOSC of the external signal must be at least
10kHz to be detected. The external clock signal duty cycle
is not significant as long as the minimum and maximum
specifications for the HIGH and LOW periods tHEO and
tLEO are observed.
While operating with an external conversion clock of a
frequency fEOSC, the LTC2483 provides better than 110dB
