MAX19710
ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3V, OVDD = 1.8V, internal reference (1.024V), CL
≈ 10pF on all digital outputs, fCLK = 7.5MHz (50% duty cycle), Rx ADC input
amplitude = -0.5dBFS, Tx DAC output amplitude = 0dBFS, CM1 = 0, CM0 = 0, differential Rx ADC input, differential Tx DAC output,
CREFP = CREFN = CCOM = 0.33F, CL < 5pF on all aux-DAC outputs, TA = TMIN to TMAX, unless otherwise noted. Typical values are at
TA = +25°C.) (Note 1)
Note 1: Specifications from TA = +25°C to +85°C guaranteed by production tests. Specifications at TA < +25°C guaranteed by
design and characterization.
Note 2: Guaranteed by design and characterization.
Note 3: The minimum clock frequency (fCLK) for the MAX19710 is 1.5MHz (typ). The minimum aux-ADC sample rate clock frequency
(ACLK) is determined by fCLK and the chosen aux-ADC clock-divider value. The minimum aux-ADC ACLK > 1.5MHz / 128 =
11.7kHz. The aux-ADC conversion time does not include the time to clock the serial data out of DOUT. The maximum con-
version time (for no averaging, NAVG = 1) will be tCONV (max) = (12 x 1 x 128) / 1.5MHz = 1024s.
Note 4: SNR, SINAD, SFDR, HD3, and THD are based on a differential analog input voltage of -0.5dBFS referenced to the amplitude
of the digital outputs. SINAD and THD are calculated using HD2 through HD6.
Note 5: Crosstalk rejection is measured by applying a high-frequency test tone to one channel and a low-frequency tone to the sec-
ond channel. FFTs are performed on each channel. The parameter is specified as the power ratio of the first and second
channel FFT test tones.
Note 6: Amplitude and phase matching are measured by applying the same signal to each channel, and comparing the two output
signals using a sine-wave fit.
