sm5023 series nippon precision circuits inc.? 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 con?ured by using an external feedback resis- tor r fo , 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 operating supply voltage range 3v operation: 2.7 to 3.6v 5v operation: 4.5 to 5.5v 4mhz to 70mhz operating frequency range (oscillation frequency is settable by external com- ponents) ?0 to 85 c operating temperature range oscillator capacitors c g , c d built-in (bn h version only) cutoff frequency setting using external feedback resistor r fo output drive capability 8ma (v dd = 2.7v) 16ma (v dd = 4.5v) output three-state function built-in high impedance output in standby mode cmos output duty level (1/2vdd) molybdenum-gate cmos process package: sot23-6 (sm5023 h) package dimensions (unit: mm) applications dip-type crystal oscillator modules series configuration ordering information 1.9 0.2 2.8 0.2 2.9 0.2 0.4 0.1 1.1 0.1 0 to 0.10 0.20min 1.6 - 0.1 + 0.2 m 0.20 0.95 0.1 0.15 - 0.05 + 0.1 version operating supply voltage range [v] recommended operating frequency range 1 [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. speci?ally, the char- acteristics can vary greatly due to crystal characteristics and mounting conditions, so the oscillation characteristics of comp onents must be carefully evaluated. oscillator circuit constants output duty level standby mode gm ratio built-in capacitance rf [k ? ] oscillator output state c g [pf] c d [pf] sm5023bndh 2.7 to 3.6 22 to 70 3 8 15 cmos operation hi-z 4.5 to 5.5 sm5023bneh 2.7 to 3.6 50 to 70 4 8 12 cmos operation hi-z SM5023CNDH 2.7 to 3.6 4 to 703 cmos operation hi-z 4.5 to 5.5 device package sm5023 h sot23-6
