POWER SUPPLIES
The LMH6521 was designed primarily to be operated on 5V power supplies. The voltage range for V
CC
is 4.75V
to 5.25V. When operated on a board with high speed digital signals it is important to provide isolation between
digital signal noise and the LMH6521 inputs. The SP16160CH1RB reference board provides an example of good
board layout.
Center Frequency is 192MHz with a 20MHz Bandwidth. Designed for 200Ω Impedance.
