SM5021 series
Crystal Oscillator Module ICs
OVERVIEW
The SM5021 series are crystal oscillator module ICs fabricated in NPC’s Molybdenum-gate CMOS, that
incorporate high-frequency, low current consumption oscillator and output buffer circuits. Highly accurate
thin-film feedback resistors and high-frequency capacitors are built-in, eliminating the need for external com-
ponents to make a stable 3rd overtone oscillator.
FEATURES
I 3rd overtone oscillation
I Oscillator capacitors CG, CD built-in
I Inverter amplifier feedback resistor built-in
(A×, B× series)
I TTL input level
I Output drive capability
• 4mA (VDD = 2.7V)
• 8mA (VDD = 4.5V)
SERIES CONFIGURATION
I Output three-state function
I Operating supply voltage range
• 2.7 to 5.5V (A×, K× series)
• 4.5 to 5.5V (B×, L× series)
I Oscillator frequency output
I 6-pin SOT (SM5021××H)
I Chip form (CF5021××)

*1. Chip form devices have designation CF5021××.
*2. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscilla-
tor frequency band is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the
oscillation characteristics of components must be carefully evaluated.
*3. The 3rd overtone frequency range using an external resistor to set the cutoff frequency.
