SM5021 series

Crystal Oscillator Module ICs

NIPPON PRECISION CIRCUITS INC.

OVERVIEW

The SM5021 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 3rd-har-

monic oscillator.

FEATURES

■ 3rd overtone oscillation

■ Capacitors CG, CD built-in

■ Inverter ampliﬁer feedback resistor built-in

(A×, B× series)

■ Output three-state function

■ 2.7 to 5.5 V supply voltage (A×, K× series)

4.5 to 5.5 V supply voltage (B×, L× series)

■ Oscillator frequency output

■ TTL input level

■ 6-pin SOT (SM5021××H)

■ 4 mA (V = 2.7 V) drive capability

■ Chip form (CF5021××)

8 mA (V = 4.5 V) drive capability
