SM5024 series Miniature-package Crystal Oscillator Module ICs OVERVIEW The SM5024 series are fundamental crystal oscillator module ICs. They feature an oscillator circuit with builtin capacitors with excellent frequency response and an output buffer with high output drive capability. They are available in miniature 6-pin packages, making them ideal as DIP-type crystal oscillators. ■ ■ ■ ■ ■ ■ ■ ■ 0.20MIN 2.8 ± 0.2 ■ (Unit: mm) + 0.1 0.15 - 0.05 1.9 ± 0.2 2.9 ± 0.2 0.4 ± 0.1 0.20 M 0 to 0.10 ■ Operating supply voltage range • 3V operation: 2.7 to 3.6V • 5V operation: 4.5 to 5.5V Up to 30MHz operating frequency range (fundamental oscillation) –40 to 85°C operating temperature range Oscillator capacitors CG, CD built-in Feedback resistor Rf built-in fO, fO/2, fO/4, fO/8 output frequency, determined by internal connection Output drive capability • 8mA (VDD = 2.7V) • 16mA (VDD = 4.5V) Output three-state function built-in High impedance outputs in standby mode CMOS output duty level (1/2VDD) Molybdenum-gate CMOS process Package: SOT23-6 (SM5024×××H) + 0.2 1.6 - 0.1 ■ PACKAGE DIMENSIONS 1.1 ± 0.1 FEATURES 0.95 0.1 APPLICATIONS ■ DIP-type crystal oscillator modules SERIES CONFIGURATION Operating Supply voltage range [V] Version Recommended Built-in capacitance [pF] operating frequency CG CD range1 [MHz] Output duty level SM5024AL1H SM5024AL2H SM5024AL3H Output INHN input frequency level Standby mode Oscillator stop function Output state Yes Hi-Z fO 2.7 to 5.5 4 to 30 8 SM5024AL4H 10 CMOS fO/2 fO/4 TTL fO/8 1. 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 characteristics can vary greatly due to crystal characteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.

BLOCK DIAGRAM VDD VSS XTN CGp Rf CDp 1/2 XT CGn 1/2 1/2 CDn Q INHN INHN = LOW active Notes. The SM5024 series reduce crystal current by limiting driving current of oscillating-stage inverter and inhibiting oscillating amplitude. Depending on the characteristics of using crystal or the mounting condition, they may not oscillate normally. Please evaluate the oscillation start-up characteristics adequately with your actual device. When this device is used for buffer application, please pay attention to input amplitude to the XT pin. If it’s low input amplitude, the SM5024 series may not operate normally.
