HMC778LP6CE handshaking sequence?
Hello. I am working with a HMC778LP6CE eval kit and I am trying to program it through SPI iface using my own hardware. I have followed the instructions on the datasheet, my timming is correct (I am...

Antonio, Sorry I didn't consider your wide bandwidth requirement in my previous response. For 5KHz bandwidth, XL001 would be our only offering. Regards,Venkat

In an older design, we used an AD7324 A to D Converter. The 13-bit output data range is 0000 (- 10V) to 1FFF (+ 10V). Two of the four channels are monitored in single-ended mode. Coding is straight...

Hello, 1) CS is only used with host mode register access2) There are no IRQ flags associated with DMA-- it's just the DREQ3) If all the data goes in, you'll eventually get a compressed output. There...

It is important to write the frequency control registers (Reg 0x3 and Reg 0x4) last and set Register 0x5=0 after all other writes to Register 0x5. This insures autocal starts after all registers have...

Yep, already tried that. ADV7511 appears to be set to expect the RGB out from the 7842. What register in that would I have to flip to get things to match?

Hi Lester, In the screenshot that you supplied, the DDS frequency is set to 10 MHz, which is much too low for the PLL to operate. Start by setting the DDS output frequency to 200 MHz and use an output...

I fixed the error by performing the EDID reset prior to the master reset - I'm not sure if it's a merge error or something that happened, but it seemed to resolve the illegal I2C access. With that, it...

Re: AD9364 AGC with the split table and phase tracking with dual receivers
In a split table LMT gain is decreased until LMT Index Limit+1 is reached and LPF gain is decreased. Once LPF gain is decreased to 0 LMT gain index below LMT Index Limit is reduced. More detail in the...

Glad to hear you have your microprocessor running the software driver and configuring the ADV7842 and ADV8005 via I2C. The ADV7842 won't handle 4K input, so you will be limited to 1080p60 on that. But...

OK, now I'm starting to understand this. The index(relative gain) has no relation to the thresholds(relative to dBFS). Exceeding the thresholds just causes an increment or decrement in the index. I...
