ADN2849

10.7 Gbps Electro-Absorption Modulator Driver Preliminary Technical Data FEATURES Data Rates up to 10.709Gb/s Typical Rise/Fall Time 27ps Power Dissipation 900mW (at 2V swing, 1V offset) Programmable Modulation Voltage up to 3V Programmable Bias Offset Voltage up to 2V Voltage-input control for offset, modulation Cross Point Adjust Range 30%- 85% www.DataSheet4U.com Selectable Data Retiming PECL/CML Data & Clock Inputs 50Ω on Chip Data & Clock Terminations Modulation Ebnable/Disable |S11|<-10dB , |S22|<-8dB at 10GHz Positive or negative 5.2 or 5.0V single supply operation Available in dice and 4x4mm 24 Lead LFCSP package ADN2849 PRODUCT DESCRIPTION The ADN2849 is a low power 10.7Gbps driver for electroabsorption modulator (EAM) applications. The modulation voltage is programmable via an external voltage up to a maximum swing of 3V when driving 50Ω. The bias offset voltage and output eye cross point are also programmable. Onchip 50Ω resistor is provided for back termination of the output. The ADN2849 is driven by AC coupled differential CML level data and has selectable data retiming to remove jitter from data input signal. The modulation voltage can be enabled or disabled by driving the MOD_ENB pin with the proper logic levels. It can operate with positive or negative (5.2V or 5.0V) supply voltage. The ADN284949 is available in a compact 4x4mm plastic package or dice format. APPLICATIONS SONET OC-192 Optical Transmitters SDH STM-64 Optical Transmitters 10Gb Ethernet IEEE802...
