SM5007 series
Crystal Oscillator Module ICs
OVERVIEW
The SM5007 series are crystal oscillator module ICs, that feature low current consumption. Highly accurate
thin-film feedback resistors and high-frequency capacitors are built-in, eliminating the need for external com-
ponents to make a stable fundamental-harmonic oscillator.
FEATURES
I Capacitors CG, CD built-in
I Standby function (oscillator stops)
I 6 µA (typ.) low standby current (5 V operation)
I Power-save pull-up resistor built-in
I Inverter amplifier feedback resistor built-in
I 3.2 mA (VDD = 4.5 V), 1.6 mA (VDD = 2.7 V)
drive capability
I 2.7 to 5.5 V supply voltage
I Low current consumption
I Oscillator frequency output
(fO or fO/2, determined by internal connection)
I 8-pin VSOP (SM5007AL×V)
I Chip form (CF5007A××)

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

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.
