Explanation of TTL and LVTTL about Keylink's RF power amplifiers
As we know, transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both thelogic function (the first "transistor") and the amplifying function (the second "transistor"), as opposed to resistor–transistor logic(RTL) or diode–transistorlogic(DTL).
There is a period of gap between 2.4 and 5 volts, which is not conducive to improving noise tolerance, but also increases system power consumptionand affects speed. So the latter part gets cut off. That's LVTTL.
In TTL "High" mode, Keylink's broadband rf power amplifier KB0525M47A can work within the voltage range of both TTL(2V min to 5V max) andLVTTL(2.5V min to 3.3V max). During normal enable (by default), our broadband rf amplifier can use TTL logic high voltage to turn off the amplifier. In Keylink's microwav amplifier, the minimum "High" level that can cover both TTL and LVTTL is 2 volts, and the maximum "Low" level that can coverboth TTL and LVTTL is 0.7 volts.
