12GHz Dual-Modulus Divide-by-4/5
DV45D
PRODUCT DESCRIPTION
DV45D is a high-speed dual-modulus divide-by-4/5 static divider in 16-pin 3x3mm
plastic QFN package. Due to its high input sensitivity, low output phase noise, and small
size, DV45D is well suited for wide-range of applications from communications,instrumentation, radios/radar, to medical etc. It has differential input and output andaccepts input frequency from 0.2GHz (sine wave, DC for square wave) to 14GHz. ATTL/LVTTL-compatible pin is provided to select modulus. A single power supply of+5V is required.

KEY FEATURES• 0.2-12GHz Bandwidth• Selectable divide-by-4 or divide-by-5 operation• Low phase noise: -140 dBc/Hz• High input sensitivity: -25 dBm• Output amplitude: 800 mVp-p (differential)• Differential input and output• 50Ω input/output impedance• Single power supply: +5V• Current consumption: 87mA
• 16-pin 3x3mm plastic QFN package
