LMH7322 Dual 700 ps High Speed Comparator with RSPECL Outputs
Checkfor Samples: LMH7322
1FEATURES DESCRIPTIONThe LMH7322isa dual comparator with 700 ps
(VCCI= +5V, VCCO= +5V) propagation delay, low dispersionof 75 ps and an
• Propagation Delay 700 ps input voltage range that extends from VCC-1.5Vto
Overdrive Dispersion20 mV-1V75 ps VEE. The devices canbe operated froma wide supply
voltage range of 2.7V to 12V. The adjustable
• Fast Rise and Fall Times 160ps hysteresis adds flexibility and prevents oscillations.
• Wide Supply Range 2.7Vto 12V Both the outputs and latch inputsof the LMH7322 are
• Input Common Mode Range Extends 200 mV RSPECL compatible. When usedin combination with
Below Negative Rail a VCCO supply voltageof 2.5V the outputs have LVDS
compatible levels.
• Adjustable Hysteresis (RS)PECL Outputs (see Application The LMH7322 is available in a 24-pin WQFN
package.
