OK, the point of PLL is clear now.
This device has two output types which are DDR LVDS and SDR CMOS. Assuming that I am using CMOS, from the ADC starting to receive data, do we have to wait 10 clock cycles before we start to latch data coming from the…
Part Number: ADS4126 The LVDS is a differential standard while the CMOS is a single ended standard.
Are both I/O standards useable for the full range of sampling rate permitted by this device?
Which of these is expected to give lower power dissipation…

I used
[ power on state ]
OE = high pull up 4.7k 1.8V
DFS = 1.125 V (R dividing)
Reset = pull up 10K 1.8V ( FPGA Power on to '0' )
Clkp/Clkm = 100 Mhz
SEN = FPGA Power on to '1'
SCLK = FPGA Power on to '1'

Part Number: ADS4126 We are clocking this part at 150MHz with low latency mode and then sampling the CMOS output in an FPGA.
Sample clock is the ADS4126 input clock (i.e. not using CLKOUT).
I am trying to understand the time at which data will be…
Haijun,
I do not see any issues with DP3 on our EVM. Are you also enabling the digital functions by writing a 0x08 to address 0x42? With address 0x25 set to 0x04 you should see a ramp. The ADC output pin for D3 is also used by D2 so you will see a couple…

Hello,
I am working on interface between analogue to digital converter ads4126 and differential amplifier driving it.
I can't find two information.
1. What is the acquisition time?
I guess about 50 % of cycle time…
Part Number: ADS4126 Hi team,
I know as of yet there are no plans to NRND the ADS4126, however I have a industrial client that plans to go into production next year and carry on for 5-7 years.
I was asked if we had any similar replacement part just…
Part Number: ADS4126 Other Parts Discussed in Thread: CDCE72010 Hi Team,
I would like to understand a bit more regarding the clocking on the ADS4126.
The datasheet shows an internal block diagram labeled CLOCKGEN. What is this? Can this device…
Other Parts Discussed in Thread: ADS4129 , ADS4126 Hi,
Is there a Verilog or VHDL model available for the LVDS interface of the ADS412x devices. Specifically I would like to get a Verilog timing model for the ADS4126 and ADS4129, but even a behavioral…
After installing the CMOS buffer, I tried to set the EVM up for LVCMOS output but couldn't. I have read the EVM User Guide and the ADS4126 Data sheet and from whatever information I could gather I tried the following -
1. Setup the EVM Jumpers as described…
