Typical Application Circuit
General Description
The MAX3942 is designed to drive high-speed optical
modulators at data rates up to 10.7Gbps. It functions as
a modulation circuit, with an integrated control op amp
externally programmed by a DC voltage.
A high-bandwidth, fully differential signal path is inter-
nally implemented to minimize jitter accumulation. When
a clock signal is available, the integrated data-retiming
function can be selected to reject input-signal jitter.
The MAX3942 receives differential CML signals (ground-
referenced) with on-chip line terminations of 50
Ω. Each
of the differential outputs has an on-chip 50
Ω resistor for
back termination. The driver is able to deliver a modula-
tion current of 40mAP-P to 120mAP-P, with an edge
speed of 23ps (typical 20% to 80%). This modulation
current reflects a modulation voltage of 1.0VP-P to 3.0VP-
P single ended or 2.0VP-P to 6.0VP-P differential.
The MAX3942 also includes an adjustable pulse-width
control circuit to precompensate for asymmetrical mod-
ulator characteristics. It is available in a compact 4mm
4mm, 24-pin thin QFN package and operates over
the -40°C to +85°C temperature range.
