A digitally programmable burst-mode 155 Mb/s transmitter for PON

This paper presents a burst-mode 155 Mb/s transmitter suitable for use in PON applications. It allows the transmitted optical power to be carefully controlled (<±5 %) over a wide temperature range (-40° to +80°). Moreover, it can be digitally programmed to work with a number of commercial lasers and to operate in Continuous-Wave transmission (at 155 Mb/s and 622 Mb/s). The chip was implemented using a BiCMOS 0.8 µm technology and occupies an area of 2.4×3.7 mm²with a power consumption of 250 mW (at 5 V).
