1 / 9 page SM5023 series NIPPON PRECISION CIRCUITS INC.—1 Miniature-package Crystal Oscillator Module ICs OVERVIEW The SM5023 series are 3rd overtone crystal oscillator module ICs. They feature built-in oscillator capacitors with excellent frequency response. As cutoff frequency can be configured by using an external feedback resis- tor Rfo, a favorable 3rd overtone oscillation can be realized with a few external components. The oscillator cir- cuit characteristics are optimized for a 3rd overtone oscillation by round blank. They also feature a built-in output buffer with high output drive capability and are available in miniature 6-pin package, making them ideal as DIP-type crystal oscillators. FEATURES I Operating supply voltage range • 3V operation: 2.7 to 3.6V • 5V operation: 4.5 to 5.5V I 4MHz to 70MHz operating frequency range (Oscillation frequency is settable by external com- ponents) I –40 to 85 °C operating temperature range I Oscillator capacitors CG, CD built-in (BN ×H version only) I Cutoff frequency setting using external feedback resistor Rfo I Output drive capability • 8mA (VDD = 2.7V) • 16mA (VDD = 4.5V) I Output three-state function built-in • High impedance output in standby mode I CMOS output duty level (1/2VDD) I Molybdenum-gate CMOS process I Package: SOT23-6 (SM5023 ×××H) PACKAGE DIMENSIONS (Unit: mm) APPLICATIONS I DIP-type crystal oscillator modules SERIES CONFIGURATION ORDERING INFORMATION 1.9 ± 0.2 2.9 ± 0.2 0.4 ± 0.1 M 0.20 0.95 0.1 0.15 - 0.05 + 0.1 Version Operating Supply voltage range [V] Recommended operating frequency range1 [MHz] 1. The 3rd overtone frequency range using an external resistor to set the cutoff frequency. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscillator frequency band is not guaranteed. Specifically, the char- acteristics can vary greatly due to crystal characteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.
