synthesizer frequency accuracy should be 0.1Hz.
I am sorry for not familiar with ad9142a.
Can AD9142A to perform just a single channel Digital analog conversion and IQ modulation ?
Or i have to use FPGA to perform NCO and IQ modulation…
as you said, AD9142a and AD9122 are similar kind of chips. When we play with single AD9142a chip. It is working fine. Now we are playing with three AD9142a chips at a time. Here we generate three DCIs signals and data from our FPGA. we just replicated…
The AD9142A has an LVDS interface to mate with your FPGA, comes in a 72-pin LFCSP package, and surpasses yoiu performance requirements. A deserializer is not necessary. AD9142A Datasheet and Product Info | Analog Devices
AD9142A makes complex modulation with I/Q data of base signal.
I am not majoring in communication engineering. So how to generate I/Q data of a square waveform or SINC waveform for AD9142A ?
I am working with AD9142a DAC chip. I am using one board which consists of two FMCs. I placed two dater cards on both FMCs. in that one dater card has two AD9142a DAC chips and Another Dater card has one AD9142a DAC chip and Isla214p520 ADC chip…
I am working on AD9142a analog device. It is a dual DAC chip. Already we are getting same frequency outputs from two DAC channels with our Existed FPGA code. but I want to generate two different datas from two DAC channel…
My customer is designing a board with AD9142A.
They know that if the NCO of AD9142A is not used, it can transmit two different real signals to IDAC and QDAC.
In this case, how much less is the output power compared to using the complex modulation output…
Nothing done for the AD9142A, however there is a AD9122 driver.
The Psi-jt for the AD9142A package is 0.11C/Watt.
