50 ohm driver

 · The 50 ohm output signal being connected to a signal generator, frequency counter, etc. Hardware. The circuit digram for the 50 ohm TTL line driver is shown in Figure 1. It uses four inverters from a 74AC14N Hex Schmitt-Trigger Inverter IC, with the remaining two inverters available for other unrelated purposes. Each of the inverters is connected to a ohm resistor, all in parallel, which . The SN is designed to drive 50 ohm lines. The SN is characterized for operation over the full military temperature range of °C to °C. The SN is .

emitter-follower transistor driving a coax cable loaded with 50 ohms at the far end. The 2n can easily drive mA for a 3V TTL swing into 50 ohms, without excessively loading down the TTL source, and the ohm termination resistor provides rapid pulldown at the end of the pulse. I'm not sure if this simple circuit will work to 25MHz. Can you suggest any single needed line driver IC or buffer or any other circuit through which we can drive 50 ohm load through LVCMOS3V3 50MHz clock (50% duty cycle) with minimum jitter on output less than 2 pico second. We have 12V, V and V on our board and we want to avoid generating any other supply. 50 and 75 ohm TTL drivers are intended to operate with a parallel termination to about + volts so they only have to sink 50 milliamps. If you intend to drive a 50 ohm transmission line which has the typical 50 ohm termination to ground, then other arrangement will need to be made like using a specialized 50 ohm line driver.

I am trying to connect a source at 5V to a load at V using a ohm Adjust the ohm resistor to account for the series resistance of your driver. No matter what line driver IC you choose, you'll want your termination circuit's Thevenin equivalent voltage to be ((VOH + VOL)/2), not ground and not Vcc. This.
