ADIS16480 and Evaluation Board Questions
(Background:) I (or more specifically my team) recently bought the ADIS16480 and the corresponding evaluation board for use with the BeagleBone Black. This board boots from a microSD card with an...
View ArticleRe: AD9959-no signal at SYNC_CLK
Another question is which pin are you trying to view the SYNC_CLK output on? SYNC_CLK should be on pin 54 which is J13 on the evaluation board. Pins 1 and 2 (J11 and J12) are SYNC_OUT and SYNC_IN...

Hi donovanpl123 Yes. I agree that there is some confusion in the illustration of how the voltage sensing is done, in the AN564 app note. In the schematic in Figure 16, L2 line must be tied to AGND. It...

I have used the ADum5241 iCoupler before but you need to run it from 5 volts in order to get it to work properly (can't use 3.3 volts). The IC is nice and small which is great but interfacing it to...

Hello Coleman,thanks for your answer.I'll obviously use a transformer to comply to the aes/ebu requirements, but my question was centered more on the aes/ebu - spdif interoperability.The anomaly you...
View ArticleCan AD820 "NC" be grounded?
I'm using the AD820 in a loop filter in an RF circuit and I would like to maximize the ground plane area. Can the "NC" pins on the AD820 (SOIC-8) be grounded without ill effects? I am also using the...

Thanks for the driver.I could understand, probably, why source code it not distributed, but what about description of communication protocol?

Re: Allowable Sample rates for the ADAU1701
Hi Coleman, Thanks for the clarification. Since 44.1K extends the lower tolerance range (rather than merely being included in it) the permissible lock range is wider on the low end than I...

Re: Further questions about DSP Code Programming and Emulator
Hi Craig, Thank you so much for replying to my question about the DSP Programming. I am sorry to reply to your answer late, because I took much time to learn and to compare your answers and the answers...

View ArticleRe: Can AD820 "NC" be grounded?
mrln55, Back in the seventies, "NC" meant that there was no internal connnection, and it's probably truefor 90% of the ICs. Unfortunately, some newbies would put "NC" on a data sheet when theymeant...
View ArticleAD9959 evaluation board control
Hi everyone, I have a question about the AD9959 evaluation board (i.e. the AD9959/PCBZ). In particular, is there a way to externally drive pins P0-P3 of the board in a way that has high input...

View ArticleRe: Refection in REFA of AD9525
Hi Jacky, If the HMC 910 is at the destination of the AD9525, then you shouldn't need a termination resistor. Perhaps your reflections are caused by the pads for the decoupling caps, but I'm still...
