The reference clock inputs are configured to accept a 1 V p-p (typical) dc offset square or sine waves centered at one-half the applied V
An internal 400 mV p-p differential voltage swing equates to 200 mV p-p applied to both REFCLK input pins.
Pipeline delays of each individual block are fixed; however, if the eight top MSBs of a tuning word are all zeros, the delay appears longer. This is due to insufficient
phase accumulation per a system clock period to produce enough LSB amplitude to the D/A converter.
If a feature such as inverse sinc, which has 16 pipeline delays, can be bypassed, the total delay is reduced by that amount.
The I/O UD CLK transfers data from the I/O port buffers to the programming registers. This transfer is measured in system clocks.
A change in duty cycle from 1 MHz to 100 MHz with 1 V p-p sine wave input and 0.5 V threshold.
Represents the comparator’s inherent cycle-to-cycle jitter contribution. Input signal is a 1 V, 40 MHz square wave. Measurement device is the Wavecrest DTS-2075.
Comparator input originates from analog output section via external 7-pole elliptic LPF. Single-ended input, 0.5 V p-p. Comparator output terminated in 50 Ω.
Avoid overdriving digital inputs. (Refer to equivalent circuits in Figure 3.)
Simultaneous operation at the maximum ambient temperature of 85°C and at the maximum internal clock frequency of 200 MHz for the 80-lead LQFP, or 300 MHz for

the thermally enhanced 80-lead LQFP, can cause the maximum die junction temperature of 150°C to be exceeded. Refer to the Power Dissipation and Thermal
Considerations section for derating and thermal management information.
