6 Electrical Specifications
Electrical specifications over recommended operating conditions with Fs = 80 MSPS (unless otherwise noted)
6.1 Definition of Test Conditions
800 mVPP
3.6 µs
1/60 kHz = 16.6 µs
Figure 6â1. Input Test Waveform
Test condition SYSTEM_INTREF refers to:
⢠All supplies at 3.3 V
⢠XTL1_MCLK & XTL2 connected at 14.31818 MHz
⢠No power downs enabled
⢠XGA at 75-Hz operation mode, internal clock, clamping enabled, internal clamp timing, coarse and fine
PGAs at midscale, bottom-level clamping, clamp code at midscale, 24-bit output mode
⢠Identical ac-coupled 0.8 Vpp ramp-shape input on all 3 channels at 60.0-kHz line rate, as shown in
Figure 5â1
⢠Use of internal bandgap and voltage references
Test condition PLL refers to:
⢠SYSTEM_INTREF, with an input signal other than the ramp-shape input test waveform of Figure 6â1.
Test condition ADC_INTREF refers to:
⢠All supplies at 3.3 V
⢠Use of internal bandgap and voltage references
⢠Use of external ADCCLK clock (SEL_ADCCLK = 1), driven at 81.92 MHz
⢠No power downs enabled
⢠Identical ac-coupled, 0.8 Vpp ramp-shape input on all three channels at 60.0-kHz line rate, as shown in
Figure 5â1
Test condition ADC_EXTREF refers to:
⢠ADC_INTREF, except: PWDN_BGAP = PWDN_REF = 1, VMID and VREFTO/BO driven from an external
source at nominal levels
Test condition ADC_PWDN refers to:
⢠ADC_INTREF, except: PWDN_ALL = 1
