Note 5: RTI (Referred-To-Input) stands for the total input-referred noise
voltage source. RTI is close to output noise voltage divided by voltage gain
(the exact equation is given in Denition of Specication section). The
equivalent noise source eN is twice the RTI value.
Note 6: The external loading at LT5554 OUT+/OUT– pins is RLOAD = 57Ω.
ROUT = RLOAD || RO = 50Ω.
Note 7: The IN+, IN–, DEC pins are internally biased. The time-constant
of input coupling capacitor sets the low frequency corner (LF) at input.
The output coupling capacitors or the transformer sets the low frequency
corner (LF) at the output. The LT5554 operates internally down to DC.
Note 8: The external loading at OUT+/OUT– pins is RLOAD = 133Ω.
ROUT = RLOAD || RO = 100Ω.
Note 9: Depending on the actual input matching conditions and frequency
of operation, the LT5554 steps involving the input attenuator tap change
may show less than 0.125dB change. These steps are GMAX –4dB, GMAX
–8dB, GMAX –12dB, and the code is given in the Programmable Gain Table.
The LT5554 monotonic operation for 0.125dB step resolution can still be
obtained by skipping any such code with a gain error excedding 0.125dB.
