Part Number: LMH6517 Tool/software: Datasheet Figure 52 (pg22) shows 4-bit address (A3..A0) and 8-bit data. What do the address and data mean in terms of gain? For example, if I want to program CHA gain=10dB and CHB gain=-5dB, what are the address and…

There is developed PCB for digital signal processing of the input baseband signal by the FPGA. The PCB has two differential baseband channels (IQ lines) . Each baseband chain has the variable attenuator ( LMH6517SQ/NOPB ), the operational…
Part Number: LMH6517 Hello,
I put the LM6517 in a board of my own design and the SPI reading and writing don’t work. I configured the chip in SPI with the MOD0 connected to ground and MOD1 floating. I put the schematic below. I originally had 5V on some…
Part Number: LMH6517 Hello all,
First the specific question then the application:
The datasheet specifies channel-channel match as +- 0.05dB.
It is not clear to me whether this holds when the gains of both channels are identical, or whether it holds…
Part Number: OPA2832 Other Parts Discussed in Thread: LMH6517 , THS4541 , THS3217 , THS3215 , OPA691 , OPA2677 , OPA2695 Hello,
I need to drive a 50 ohm load up to 8.9Vpp (23dBm) 5 MHz to 30 MHz from the output of a LMH6517 programmable gain amplifier. The LMH6517…
Part Number: LMH6517 Hello,
The datasheet surface finish on this part simply lists 'SN'. Is there any barrier Nickel or other metal beneath the tin that might help mitigate the possibility of Tin Whisker growth on the component? Or is it really…
Part Number: LMH6517 Other Parts Discussed in Thread: LMH6882 , LMH6521 All the circuit examples in the LMH6517 data sheet and the associated Eval board documentation seem to show ac coupled inputs using capacitors or balun transformers.
In our application…

Hi,
I'm looking for a VGA solution to satisfy the requirements below:
1. support 5V supply
2. gain step size:0.5-1dB
3. gain range: -10dB to 15dB
4.BW: DC-130MHz
5. parallel…
Part Number: LMH6517 In the LMH6517 datasheet, it says to put the solder paste as 4 squares instead of one big square for the thermal pad. I put a picture below.
In PowerPad layout guidelines http://www.ti.com/lit/pdf/sloa120, it says to use the full…
