CF5019ALC-2規(guī)格書詳情

OVERVIEW

The CF5019 series are high-frequency, 3rd overtone crystal oscillator module ICs. They incorporate an oscillator circuit and an output buffer that operate at high frequency on a single chip. The oscillator circuit employs CMOS inverters and a built-in damping resistor RD, reducing the crystal current compared with existing devices. The damping resistor RD is fabricated using NPC’s unique high-precision thin-film resistor technology, which suppresses oscillator characteristic variations due to changes in temperature and voltage to a minimum. The CF5019 series can be utilized to construct stable, high-frequency, 3rd overtone crystal oscillators.

FEATURES

■ RD built-in to reduce crystal current in the oscillator circuit

■ 2.25 to 3.6V operating supply voltage range

■ Recommended operating frequency range (varies with version)

? 2.5V operation: 60 to 155MHz

? 3.0V operation: 60 to 170MHz

■ – 40 to 85°C operating temperature range

■ Oscillator capacitors with excellent frequency response built-in

■ Feedback resistors with good temperature characteristics built-in

■ Standby function

? High impedance in standby mode, oscillator stops

■ Low standby current

? Power-saving pull-up resistor built-in

■ Oscillation detector function

■ CMOS output duty level (1/2VDD)

■ 50 ± 5 output duty (at 1/2VDD)

■ 30pF output load (3.3V operation)

■ Molybdenum-gate CMOS process

■ Chip form (CF5019AL×)

APPLICATIONS

■ Crystal oscillator modules (3rd overtone oscillation)
