.
Note 6:
Differential Gain and Phase are measured using a Tektronix
TSG120 YC/NTSC signal generator and a Tektronix 1780R Video
Measurement Set. The resolution of this equipment is 0.1% and 0.1
°
. Nine
identical MUXs were cascaded giving an effective resolution of 0.011%
and 0.011

.
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
May require a heat sink.
Note 3:
The LT1675/LT1675-1 are guaranteed to meet specified
performance from 0
