i T6145 Duobinary Encoder and Driver Amplifier
(Preliminary Information)
Description
The i T6145 bines a duobinary encoder, driver amplifier, and fifth-order Bessel lowpass filter in a pact module. It is designed for use in the transmitters (transponders) of long-haul duobinary optical munication links. The microchip module is suitable for use in standard 300-pin MSA modules and is housed in a rugged enclosure. The output of the i T6145 is a duobinary encoded signal with the correct bandwidth and amplitude to directly drive a M-Z optical modulator. The output level is adjustable from 5 to 9 Vpp to allow for variations in modulator Vpi. An internal detector provides a temperature-stable DC voltage that is proportional to the output data amplitude, facilitating the use of AGC loops to set the output level. The clock and data inputs can be driven either differentially for maximum sensitivity, or single ended with the unused inputs terminated in 50 ohms. plete, pact duo-binary transmitter solution Adjustable output voltage from 5.0 to 9.0 Vpp Power dissipation: 5 W 16-mm SMT ceramic package with bottom pad grounding and heat sinking Differential data and clock inputs Integral output level detector for AGC loop control
