MaxLinear Inc. (NYSE: MXL), a provider of radio frequency (RF) and mixed-signal integrated circuits for the connected home and wired and wireless infrastructure markets, has released the MxL9203, a quad-channel linear Mach-Zehnder (MZ) modulator driver for next-generation 200Gbps dense wave division multiplexing (DWDM) coherent systems, the company said.
The MxL9203 has a per-channel data rate of 32Gbaud with differential input and single-ended output. The MxL9203 features a serial peripheral interface (SPI) to perform all control and monitoring functions, which greatly simplifies module peripheral circuitry design and eliminates the need for external analog / digital conversion (DAC/ADC) and op-amp components that are required by conventional driver devices.
A programmable input gain equalizer compensates for high frequency loss from the printed circuit board (PCB) and the package, and provides bandwidth optimization capability to support up to 260Gbps data rate. The MxL9203 supports both legacy manual gain control mode and automatic gain control mode.
The device also integrates broadband bias tee to maintain optimal power dissipation. The MxL9203 is available in a small 14mm x 9mm SMT package that makes it ideal for the next-generation CFP-DCO or smaller form-factor module design for telecom applications where maximizing face-plate density and minimizing power dissipation are critical.
MaxLinear is headquartered in Carlsbad, California.
