1 _{All ac specifications tested with a single-ended, 2.0 V p-p encode on ENCODE and ENCODE floating.}
2 _{The image spur is included in the SINAD specification.}
3 _{The image spur is not included in the SFDR specification.}
4 _{The image spur is at fS/2 – AIN; the offset spur is at fS/2.}
5 _{F1 = 70 MHz, F2 = 73 MHz.}
6 _{Parts are tested with 360 MSPS encode. Device can be clocked at lower encode rates, but specifications are not guaranteed. Specifications are guaranteed by design}
for encode 360 MSPS ± 1%.
7 _{Pipeline latency is exactly 74 cycles with an additional tPD required for data to emerge.}
