M02044CG-31 Datasheet, PDF (13/22 Pages) M/A-COM Technology Solutions, Inc. – 3.3/5V Limiting Amplifier for Applications from 100 Mbps to 622 Mbps

Functional Description
allow data to propagate only when the signal is above the user's bit-error-rate requirement. It therefore inhibits the
data outputs toggling due to noise when there is no signal present (“squelch”).
In order to implement this function, LOS should be connected to the JAM pin shown in Figure 3-6, thus forcing the
data outputs to a logic “one” state when the signal falls below the threshold.

Voltage Regulation
The M02044 contain an on-chip voltage regulator to allow both 5V and 3.3V operation. When used at 5V, the on-
chip regulator is enabled and the digital inputs and outputs are compatible with TTL 5V logic levels.
