On offer are a number of individually priced NEW old stock (NOS) AD9854ASQ Direct Digital Synthesis (DDS) chips by Analog Devices.

Comparing to other AD985x, AD9854 provides I&Q Dual-DAC output system which suits them to almost any modulation scheme directly from a digital input. These are the high speed ASQ variant, non-RoHS, with the following specifications (check AD9854 Datasheet for details) :

• 0 ~ 120MHz output frequency
• 300 MHz internal clock rate max
• 48 bits frequency control tuning i.e. (1uHz @ fref = 300MHz)
• 14 bit phase control
• 12 bit dual DACs - Quadrature I&Q outputs
• 4x ~ 20x programmable Reference Clock Multiplier
• 3.3V Single Supply

You may find wonderful app notes and on-line design tools for this DDS synthesizer from manufacturer's site. Searching on the internet will certainly give you numerious AD985x based projects on

• Receiver VFO / LO
• Precise clock generator
• Transmitter multimode modulator/exciter
• RF Sweep / Signal Generator
• Spectrum Analyzer (SA) or Vector Network Analyzer (VNA)

Item is eligible for combined shipment to save shipping cost.

The chip will be sent out via registered mail service with tracking number provided.

Notes: There is a metal pad on the chip base which is conventionally soldered to a copper PCB groundplane. The chip runs hot and this is where most heat flows to keep it running safely so be aware.
