Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: ADS42JB46 Hello,
I was wondering if you can provide HDL simulation models (VHDL or verilog) of this data converter or any in his family.
Thanks,
Joffrey Doly
Part Number: ADS42JB46 Hi everyone,
I have a question about the SPI control signals' logic level of ADS42JB46,
1) I see that this AD part can support both 1.8V and 3.3V, so how can I choose the logic level as 1.8V or 3.3V?
2) what's more, I don't…
Part Number: ADS42JB46 Other Parts Discussed in Thread: ADS42JB49 Hi TI,
I want to know the detailed PLL structure in the ADC chip.
I find something confused in some sigma-delta ADC, that is the PLL for JESD204B.
Something like: "PCLK", "IFX_PCLK",,, so…
Part Number: ADS42JB46 Hi TI,
I design one ADS42JB46 Test Board following the official design 'ADS42JB46EVM'.
Now I want to test the performance(ENOB) of ADS42JB46 chip.
I want to test ENOB under several specific frequency as the you do, so I…
Part Number: ADS42JB46 Hi everyone,
Recently, I am trying to config ADS42JB46 which is based on SPI, and I want to use its 'Test Pattern',clock pattern, to do a simple test but failed. The results like this:
And the ILA sequence after BCBC..…
Part Number: ADS42JB46 Hi everyone,
I don't know why input analog bandwidth is larger than sample rate for ADS42JB46, whose analog bandwidth is about 900 MHz, but its MAX sample rate is 160 Msps,
and I have a question about JESD204B, why ADS42JB46…
Part Number: ADS42JB46 Could you please share the ADS42JBX9EVM PCB design file? My customer want a reference to improve their layout. Thanks in advance!
Part Number: ADS42JB46 1) Looking at the ADS42JBXXEVM-SCH, why is the SYSREF driven LVPECL, while the CLKIN is driven LVDS?
2) Per the datasheet page 10, the JESD204B Digital Outputs are supposed to be externally terminated with 50 ohms to IOVDD. None…
Hi John,
It is also possible the input may be saturated. Please refer to table 13 in datasheet and adjust the input full scale range to the maximum of 2.5Vpp.
Thanks,
Eben.
Part Number: ADS42JB46 Hi Team,
My customer is interested in getting an understanding of the minimum input amplitude possible on the ADS42JB46EVM + TSW14J50.
Their radio signal can come in as low as -110dBm and through a series of components, gain about…
