MAXIM Integrated Products, represented by Arrow Electronics , has introduced the MAX3942 modulator driver.
Operating from a single -5.2V or +5.0V supply, it consumes only 125mA of current.
The MAX3942 has a 23ps 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 serialiser and operates with a selectable retiming latch to minimise jitter accumulations in the transmit path.
An integrated 50‡ termination at the input and 50‡ back termination at the output reduces external component count.
The MAX3942 is designed for SONET OC192/SDH STM64 systems, 10GbE, metro, long-haul, point-to-point, and dense wave-division multiplexing (DWDM) applications and differentially drives a Mach-Zehnder modulator or direct-modulated packaged laser.
The MAX3942 operates over the -40ºC to 85ºC temperature range and is packaged in a 4mm x 4mm, 24-pin TQFN.
