ADN2849中文资料亚德诺数据手册PDF规格书

PRODUCT DESCRIPTION

The ADN2849 is a low power 10.7Gbps driver for electro-absorption 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. On-chip 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.
