Test Conditions/Comments
See Figure 28 for maximum toggle rate
With 20 pF load and up to 40 MHz
With 20 pF load
DAC lower limit is 0 Hz; however, the minimum slew rate
for FDBK_IN dictates the lower limit if using CMOS or HSTL
outputs
Single-ended (each pin internally terminated to AVSS)
Range depends on DAC R
Outputs connected to a transformer whose center tap is
grounded
