SM5022 series
Crystal Oscillator Module ICs
OVERVIEW
The SM5022 series are crystal oscillator module ICs
fabricated in NPC’s Molybdenum-gate CMOS, that
incorporate high-frequency, low current consump-
tion oscillator and output buffer circuits. Highly
accurate thin-film feedback resistors and high-fre-
quency capacitors are built-in, eliminating the need
for external components to make a stable fundamen-
tal-harmonic oscillator.
FEATURES
s Up to 30MHz operation
s Fundamental oscillation
s Capacitors CG, CD built-in
s Inverter amplifier feedback resistor built-in
s TTL input level
s 4 mA (VDD = 2.7 V) drive capability
8 mA (VDD = 4.5 V) drive capability
SERIES CONFIGURATION
s Output three-state function
s 2.7 to 5.5 V supply voltage (A× series)
4.5 to 5.5 V supply voltage (B× series)
s Oscillator frequency output (fO, fO/2, fO/4, fO/8
determined by internal connection)
s 6-pin SOT (SM5022××H)
s Chip form (CF5022××)
