Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 3:
The rise time at VOUT is measured between 0.5V and 1.5V. of a device may be impaired.
Note 4:
Bandwidth is calculated using the 10% to 90% rise time equation:
Note 2:
Specifications over the –40°C to 85°C operating temperature BW = 0.35/rise time. range are assured by design, characterization and correlation with
Note 5:
RF performance is tested at 1800MHz statistical process controls.
Note 6:
Guaranteed by design. 5508fa 2
