Part Number: ADS54RF63 Other Parts Discussed in Thread: ADS5440 If Low Jitter Clock Solution For High-Speed must be used when set the sample rate to higher than 500Msps.
The datasheet shows this CLK solution is useful, but when I study the EVM boards…
Cedrick,
The customer will have to verify this interface as I know nothing about the Crosslink FPGA. Attached is the User's Guide for the ADS5474EVM which contains the board schematic. TI also has two adapters (both attached) they may used depending…
Other Parts Discussed in Thread: ADS5444 , ADS54RF63 , ADS5440 , ADS5474 The ADS54RF63 datasheet states it is Pin-Similar/ Compatible to 12-, 13-, and 14-Bit ADS5440/ ADS5444/ ADS5474. However, it does not state how the NC pins 47,48,49,50 behave. In…
Other Parts Discussed in Thread: ADS5440 , ADS5400 , ADS5474 On ADS5440/44/63/74 EVM card, there are two 10-ohm series resistors R19 and R20. What is the function of these series resistors? Are they just series terminations? Refer to TI User's Guide SLAU194A…
Couple of quick things Akash,
1. Where is your DC bias current path for the V+ inputs to the op amps?
2. This differential I/O op amp circuit sometimes has a common mode oscillation - probably not here, but we did see that in the OPA838 decomp device…
