Any one know of a good reference design for a driver for an input to
unit with a 50ohm impedance and that's looking for 8 to 11VDC as a
"high" and "-1 to 2VDC for a logic 0? Needs to have a fast (50nsec)
rise time.
I have been pondering just driving a transistor cable of handling about
500mA with the collector ties to the mid-junction of two 50ohm
resistors hooked in series. The high side resistor connected to 20VDC
and the other resistor connected to ground.
Any references or suggestions will be greatly appreciated!
Thanks!
