TMOD0110G

The TMOD0110G is a gallium arsenide (GaAs) integrated circuit used to provide voltages to drive optical modulators in high-speed, non-return-to-zero (NRZ) transmission systems. The TMOD0110G is designed for use in SONET OC-192 and SDH STM-64 transmitter applications. An input buffer with complementary inputs and 50 terminations provides an excellent match for differential sources. The eye crossover (duty cycle), modulator dc offset, and peak-to-peak output voltage swing are all useradjustable by setting the dc voltage on the respective control pin. The differential outputs allow the TMOD0110G to drive lithium niobate modulators. For single-ended output EML applications, the user may terminate the unused output with a load that best matches the load of the EML. The TMOD0110G can be tuned at the factory to operate on either a 6.8 V or a 5.2 V power supply. The TMOD0110G is available in a 32-lead hermetic, surface-mount package.
