Abstract: This disclosure describes techniques for shifting the cross-point of a digital signal in an optical transmitter. The cross-point shifting techniques may use multiple differential transconductors with their common polarity outputs coupled together to shift the cross-point of a signal. Using multiple differential transconductors in this manner may increase the balance between the positive and negative polarities of the resulting cross-point shifted signal relative to other types of cross-point shifting techniques, which may improve the quality of an optical signal generated by an optical transmitter.

Abstract: A loss-of-signal (LOS) detector includes a variable gain amplifier with an input receiving an input signal, a threshold comparator with a first input receiving a signal derived from an output of the variable gain amplifier, a second input receiving a reference level and an output providing a loss-of-signal indication signal. The variable gain amplifier has a gain control input receiving a gain control signal derived from the output of the threshold comparator and such that the gain of the variable gain amplifier is set to a lower value when the loss-of-signal indication signal is active, and set to a higher value when the loss-of-signal indication signal is not active. Accordingly, the LOS detector needs only one decision level for both of the LOS and NotLOS decisions, which is set in the linear range of the signal detector so that the hysteresis is reproduced precisely.
