1 / 21 page WF5027 series SEIKO NPC CORPORATION —1 Crystal Oscillator Module ICs OVERVIEW The WF5027 series are miniature crystal oscillator module ICs. The oscillator circuit stage has voltage regula- tor drive, significantly reducing current consumption and crystal current, compared with existing devices, and significantly reducing the oscillator characteristics supply voltage dependency. There are 3 pad layout package options available for optimized mounting, making these devices ideal for miniature crystal oscillators. FEATURES I Wide range of operating supply voltage: 1.60 to 3.63V I Regulated voltage drive oscillator circuit for reduced power consumption and crystal drive current I Optimized low crystal drive current oscillation for miniature crystal units I 3 pad layout options for mounting • 5027A ×, M×, Q× series: for Flip Chip Bonding • 5027B ×, N×, R× series: for Wire Bonding (type I) • 5027C ×, P×, S× series: for Wire Bonding (type II) I Recommended oscillation frequency range For fundamental oscillator • Low frequency version: 20MHz to 60MHz • High frequency version: 60MHz to 100MHz For 3rd overtone oscillator • Low frequency version: 40MHz to 110MHz • High frequency version*1: 110MHz to 180MHz *1: under development I Multi-stage frequency divider for low-frequency output support: 0.9MHz (min) I Frequency divider built-in (for fundamental oscil- lator) • Selectable by version: fO, fO/2, fO/4, fO/8, fO/16, fO/32, fO/64 I −40 to 85°C operating temperature range I Standby function • High impedance in standby mode, oscillator stops I CMOS output duty level (1/2VDD) I 50 ± 5% output duty I 15pF output drive capability I Wafer form (WF5027 ××) Chip form (CF5027 ××) APPLICATIONS I 3.2 × 2.5, 2.5 × 2.0, 2.0 × 1.6 size miniature crystal oscillator modules ORDERING INFORMATION Device Package WF5027 ××–4 Wafer form CF5027 ××–4 Chip form |
