SM5007 series
FUNCTIONAL DESCRIPTION
Standby Function
The oscillator stops when INH goes LOW. When the oscillator stops, the oscillator output on Q changes as
shown in the following table.
INH
Q
HIGH (or open)
LOW
fO or fO /2 output frequency
AA series : LOW
AL series : High impedance
Oscillator
Normal operation
Stopped
Power-save Pull-up Resistance
The INH pull-up resistance changes in response to the input level (HIGH or LOW). When INH goes LOW
(standby state), the pull-up resistance becomes large to reduce the current consumption during standby.
