WF5028

www.DataSheet4U.com WF5028 series 0.8V operation Crystal Oscillator Module ICs OVERVIEW The WF5028 series are miniature crystal oscillator module ICs. The devices are fabricated using a proprietary low voltage process, enabling 0.8V operation. The pad layouts are selective from 3 types depending on package structures, mounting methods, which are suitable for miniature crystal oscillators. The WF5028 series can be used to realize ultra miniature, ultra low voltage crystal oscillators. FEATURES I I I I I Wide range of operating supply voltage: 0.8 to 2.0V Optimized low crystal drive current oscillation for miniature crystal units 3 pad layout options for mounting WF5028A× series: for Flip Chip Bonding CF5028B× series: for Wire Bonding (type I) CF5028C× series: for Wire Bonding (type II) Recommended oscillation frequency range: 20MHz to 50MHz Multi-stage frequency divider for low-frequency output support: 0.75MHz (min) I I I I I I I Frequency divider built-in Selectable by version: fO, fO/2, fO/4, fO/8, fO/16, fO/32, fO/64 −40 to 85°C operating temperature range Standby function High impedance in standby mode, oscillator stops CMOS output duty level (1/2VDD) 50 ± 5% output duty 15pF output drive capability Wafer form (WF5028××) Chip form (CF5028××) APPLICATIONS I 3.2 × 2.5, 2.5 × 2.0, 2.0 × 1.6 size miniature crystal oscillator modules ORDERING INFORMATION Device WF5028××–4 CF5028××–4 Package Wafer form Chip form SEIKO NPC CORPORATION —1 www.DataSheet4U...
