5 / 6 page 3.3 V / 5V 622 Mb/s Transimpedance Amplifier F0100209B ♦ ♦ ♦ ♦ ♦ General Description A transimpedance amplifier is applied as a pre-amplifier which is an amplifier for a faint photo-current from a PIN photo diode (PD). The performance in terms of sensitivity, band- width, and so on, obtained by this transimpedance amplifier strongly depend on the capaci- tance brought at the input terminal; therefore, “typical”, “minimum”, or “maximum” parameter descriptions can not always be achieved according to the employed PD and package, the assembling design, and other technical experts. This is the major reason that there is no product lineup of packaged transimpedance amplifiers. Thus, for optimum performance of the transimpedance amplifier, it is essential for cus- tomers to design the input capacitance carefully. Hardness to electro-magnetic interference and fluctuation of a power supply voltage is also an important point of the design, because very faint photo-current flows into the transimpedance amplifier. Therefore, in the assembly design of the interconnection be- tween a PD and a transimpedance, noise should be taken into consideration. ♦ ♦ ♦ ♦ ♦ Low Voltage Operation The F0100209B features a single 3.3 V supply operation, which is in great demand re- cently, because most of logic IC’s operate with the supply voltage of 3.3 V. The analog IC’s with a single 3.3 V supply for use in fiber optic communication systems are offered by only SEI. ♦ ♦ ♦ ♦ ♦ Recommendation SEI basically recommends the F08 series PINAMP modules for customers of the transimpedance amplifiers. In this module, a transimpedance amplifier, a PD, and a noise filter circuit are mounted on a TO-18-can package hermetically sealed by a lens cap, having typically a fiber pigtail. The F08 series lineups are the best choice for customers to using the F01 series transimpedance amplifiers. SEI’s F08 series allows the customers to resolve troublesome design issues and to shorten the development lead time. ♦ ♦ ♦ ♦ ♦ Noise Performance The F0100209B based on GaAs FET’s shows excellent low-noise characteristics com- pared with IC’s based on the silicon bipolar process. Many transmission systems often demand superior signal-to-noise ratio, that is, high sensitivity; the F0100209B is the best |
