5 August 2003 Sunnyvale, CA Lightwave - Maxim Integrated Products introduces the MAX3942 modulator driver. Operating from a single -5.2V or +5.0V supply, the MAX3942 consumes only 125mA of current. The MAX3942 has a 23-psec edge speed with a programmable modulation current up to 120mA (6V peak-to-peak into differential 50 ohm loads).
This device also features polarity control to ensure an easy interface to any serializer and operates with a selectable retiming latch to minimize jitter accumulations in the transmit path. An integrated 50Ω termination at the input and 50Ω back termination at the output reduces external component count.
The MAX3942 is designed for SONET OC-192/SDH STM-64 systems, 10 Gigabit Ethernet, metro, long-haul, point-to-point, and DWDM applications and differentially drives a Mach-Zehnder modulator or direct-modulated packaged laser. The MAX3942 operates over the -40° to 85°C temperature range and is packaged in a 4x4 mm, 24-pin thin QFN. Prices start at $64.00 (1000-up, FOB USA).
