WF5025 series Crystal Oscillator Module ICs OVERVIEW The WF5025 series are miniature crystal oscillator module ICs. They feature a damping resistor RD matched to the crystal's characteristics to reduce crystal current. The pad layout is arranged for flip chip mounting, which gives the pattern design more flexibility, even for mounting ultra-miniature crystal oscillators that provide almost no space for wiring patterns. They support fundamental oscillation and 3rd overtone oscillation modes. The WF5025 series can be used to correspond to wide range of applications. FEATURES I I I I I I Pad layout optimized for flip chip mounting Miniature-crystal matched oscillator characteristics Operating supply voltage range • 2.5V operation: 2.25 to 2.75V • 3.0V operation: 2.7 to 3.6V Recommended operating frequency range • For fundamental oscillator - WF5025AL×: 20MHz to 50MHz - WF5025BL1: 20MHz to 100MHz • For 3rd overtone oscillator - WF5025ML×: 70MHz to 133MHz −40 to 85°C operating temperature range Oscillator capacitor with excellent frequency characteristics built-in I I I I I I I I I Oscillator circuit with damping resistor RD builtin for reduced crystal current Standby function • High impedance in standby mode, oscillator stops Low standby current • Power-saving pull-up resistor built-in Oscillation detector function Frequency divider built-in (WF5025AL×) • varies with version: fO, fO/2, fO/4, fO/8, fO/16, fO/32 CMOS output duty level (1/2VDD) 50 ± 5% output duty @ 1/2VDD 30pF output load Molybdenum-gate CMOS process SERIES CONFIGURATION Version Operating supply voltage [V] Oscillation mode Recommended Output operating frequency current range (fundamental (VDD = 2.5V) [mA] oscillation)*1 [MHz] Standby mode Output frequency fO fO/2 2.25 to 3.6 Fundamental 20 to 50 4 fO/4 fO/8 fO/16 fO/32 2.25 to 3.6 Fundamental 20 to 100 70 to 80 2.25 to 3.6 3rd overtone 80 to 100 90 to 133 8 fO CMOS Yes Hi-Z 8 fO CMOS Yes Hi-Z CMOS Yes Hi-Z Output duty level Oscillator stop function Output state WF5025AL1 WF5025AL2 WF5025AL3 WF5025AL4 WF5025AL5 WF5025AL6 WF5025BL1*2 WF5025MLA (WF5025MLB) WF5025MLC *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. *2. The WF5025BL1 has a higher maximum operating frequency, hence the negative resistance is also larger than in the WF5025AL× devices. Note. These versions in parentheses ( ) are under development. Please ask our Sales & Marketing section for further detail.

NIPPON PRECISION CIRCUITS INC.—12 WF5025 series FUNCTIONAL DESCRIPTION Standby Function When INHN goes LOW, the oscillator stops and the oscillator output on Q becomes high impedance. Version WF5025AL× WF5025BL1, ML× WF5025AL×, BL1, ML× INHN HIGH (or open) LOW Q Any fO, fO/2, fO/4, fO/8, fO/16 or fO/32 output frequency fO High impedance Stopped Oscillator Normal operation Power-save Pull-up Resistor The INHN pull-up resistance changes in response to the input level (HIGH or LOW). When INHN goes LOW (standby state), the pull-up resistance becomes large to reduce the current consumption during standby.
