SM5009 series Crystal Oscillator Module ICs OVERVIEW The SM5009 series are crystal oscillator module ICs that incorporate low crystal current type oscillating circuit to limit oscillator-stage current, so that they can reduce crystal current lower than the existing products. Since the oscillating circuit has oscillator capacitors with excellent frequency response and feedback resistor built-in, just connecting crystal realizes stable fundamental oscillation responding up to 40MHz. The SM5009 series are ideal for SMD type crystal oscillator using a strip-shaped crystal blank. FEATURES I I I I I I I I Low crystal current oscillator Up to 40MHz operating frequency range (fundamental oscillation) Operating supply voltage range 3V operation: 2.7 to 3.6V 5V operation: 4.5 to 5.5V –40 to 85°C operating temperature range Oscillation capacitors CG, CD built-in Inverter amplier feedback resistor built-in Standby function Oscillator stops (AL series), high impedance in standby mode Low standby current I I I I I I I Power-save pull-up resistor built-in (AL series) Frequency divider built-in (fO, fO/2, fO/4, fO/8, fO/16, fO/32 determined by internal connection) Output drive capability AL×, AN×, AK×, CN×: 16mA (VDD = 4.5V) AH×: 4mA (VDD = 4.5V) Output load: CL = 50pF max. Output duty level CMOS level (1/2 VDD): AL×, AN×, AH×, CN× TTL level (1.4V): AK× Molybdenum-gate CMOS process 8-pin SOP (SM5009×××S) Chip form (CF5009×××) Standby mode Output frequency fO fO/2 fO/4 fO/8 f……
