14 / 232 page  6.6 Electrical Characteristics - AC Specifications Typical values at TA = +25°C, minimum and maximum values over operating free-air temperature range, typical supply voltages, FCLK = 10.24GHz, 8b/10b encoding, IFS_SWITCH = 20.5mA, single tone amplitude = 0dBFS, SE DEM and Dither (DEM_ADJ = 1 below 750MHz and DEM_ADJ = 0 above 750MHz), 8b/10b encoding, unless otherwise noted. FDAC = FCLK in NRZ, RTZ and RF modes and FDAC = 2×FCLK in DES1X and DES2XL/H modes. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT MODE INDEPENDENT PARAMETERS FCLK DAC clock rate 0.8 10.4 GHz BW Analog output bandwidth (–3dB) Excluding sinx/x response. Useable bandwidth may exceed the –3dB point. IFS_SWITCH = 20.5mA 12.15 GHz Excluding sinx/x response. Useable bandwidth may exceed the –3dB point. IFS_SWITCH = 41mA 11.95 Crosstalk Isolation between channel A (DACOUTA+/–) and channel B (DACOUTB+/-), fOUT = -25MHz offset on victim channel fOUT = 97MHz, NRZ mode 92 dBc fOUT = 1897MHz, NRZ mode 88 dBc fOUT = 3897MHz, NRZ mode 84 dBc fOUT = 5897MHz, RF mode 80 dBc fOUT = 7897MHz, RF mode 74 dBc DAC OUTPUT TIME DOMAIN CHARACTERISTICS tRISE 10% to 90%(1) JMODE 0, 1x Interpolation 42 ps tFALL 90% to 10%(1) JMODE 0, 1x Interpolation 42 ps fCLK DC Feedthrough Relative to fullscale sinewave at 1GHz NRZ Mode, fOUT = DC (mid-code), DEM/Dither off 58 dBc NRZ Mode, fOUT = DC (mid-code), DEM/Dither on 61 dBc DES2XL Mode, fOUT = DC (mid- code), DEM/Dither off 58 dBc DES2XL Mode, fOUT = DC (mid- code), DEM/Dither on 61 dBc 2×fCLK DC Feedthrough Relative to fullscale sinewave at 1GHz DES2XL Mode, fOUT = DC (mid- code), DEM/Dither off 61 dBc DES2XL Mode, fOUT = DC (mid- code), DEM/Dither on 67 dBc DAC39RF10-SP, DAC39RF10-SEP DAC39RFS10-SP, DAC39RFS10-SEP SBAS932A – MARCH 2024 – REVISED FEBRUARY 2026 www.ti.com 14 Submit Document Feedback Copyright © 2026 Texas Instruments Incorporated Product Folder Links: DAC39RF10-SP DAC39RF10-SEP DAC39RFS10-SP DAC39RFS10-SEP |
