6.11.8 TX Typical Characteristics at 30 MHz and 600 MHz (continued)

Typical values at TA = +25°C with nominal supplies. Default conditions: TX input data rate = 125 MSPS, fDAC = 6000

MSPS (48x interpolation), interleave mode, 1st Nyquist zone output, PLL clock mode with fREF = 500 MHz. Additional default

conditions for all plots, AOUT = –1 dBFS, DSA = 0 dB, Sin(x)/x enabled, Dither = 1, DSA calibrated, TX Clock Dither Enabled

Integrated Phase Error = PhaseOUT(DSA Setting) –

PhaseOUT(DSASetting = 0)
