Part Manufacturer: Maxim


Part Description: MAX3942 DS

Part Details:

19-2934; Rev 1; 6/07 10Gbps Modulator Driver MAX3942 General Description Features The MAX3942 is designed to drive high-speed optical 23ps Edge Speed modulators at data rates up to 10.7Gbps. It functions as a modulation circuit, with an integrated control op amp Single-Ended Modulation Voltage Up to 3VP-P externally programmed by a DC voltage. Differential Modulation Voltage Up to 6VP-P A high-bandwidth, fully differential signal path is inter- Selectable Data-Retiming Latch nally implemented to minimize jitter accumulation. Whena clock signal is available, the integrated data-retiming Up to 10.7Gbps Operation function can be selected to reject input-signal jitter. 50 On-Chip Input and Output Terminations The MAX3942 receives differential CML signals (ground- Pulse-Width Adjustment referenced) with on-chip line terminations of 50. Eachof the differential outputs has an on-chip 50 resistor for Enable and Polarity Controls back termination. The driver is able to deliver a modula- ESD Protection tion current of 40mAP-P to 120mAP-P, with an edgespeed of 23ps (typical 20% to 80%). This modulation Applications current reflects a modulation voltage of 1.0VP-P to 3.0VP-P single ended or 2.0VP-P to 6.0VP-P differential. Mach Zehnder Modulators The MAX3942 also includes an adjustable pulse-width Packaged Direct-Modulated Lasers control circuit to precompensate for asymmetrical mod- SONET OC-192 and SDH STM-64 Transmission ulator characteristics. It is available in a compact 4mm Systems 4mm, 24-pin thin QFN package and operates overthe -40°C to +85°C temperature range.
