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 pack-

age 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

ꢀ Wide range of operating supply voltage: 0.8 to 2.0V

^ꢀOptimized low crystal drive current oscillation for

miniature crystal units

ꢀ Frequency divider built-in

• Selectable by version: f , f /2, f /4, f /8, f /16,

f /32, f /64

ꢀ 3 pad layout options for mounting

ꢀ −40 to 85°C operating temperature range

• 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

^ꢀStandby function

• High impedance in standby mode, oscillator

stops

^ꢀCMOS output duty level (1/2VDD)

^ꢀ50 5ꢀ output duty

ꢀ 15pF output drive capability

^ꢀWafer form (WF5028××)

Chip form (CF5028××)

^ꢀMulti-stage frequency divider for low-frequency

output support: 0.75MHz (min)

APPLICATIONS

^ꢀ3.2 × 2.5, 2.5 × 2.0, 2.0 × 1.6 size miniature crystal oscillator modules
