Hittite Microwave unveils 32Gb/s optical modulator drivers
By TVTechnology
Hittite Microwave has introduced two new optical modulator drivers, the HMC1068 and the HMC1069, which are available in the die form and are well suited for driver-integrated chip-and-wire module designs for 100Gb/s DP-QPSK systems.
The HMC1068 and HMC1069 support data rates up to 32Gb/s and exhibit less than 0.3ps additive jitter and +/- 5ps group delay variation. The output signal amplitude and the crosspoint are adjustable through the control pins. The integrated peak-detector feature is used for monitoring the output voltage signal levels during normal operation.
Operating over a wide supply voltage range and featuring scalable power dissipation for varying output drive requirements, the HMC1068 and the HMC1069 are well suited for Lithium Niobate Mach-Zender Modulators when used in cascade configuration, delivery 30dB and a 7.5Vpp output signal. The HMC1069 can also be used in standalone mode as a single-stage amplifier where lower-output swing levels are required.
