TAILIEUCHUNG - Temperature control of pseudo noise generator based optical transmitter using airflow and heat sink profile at high speed transceiver logic IO standard
Junction temperature is the final temperature of any device, after that device became dead. In this paper, junction temperature of target device . Pseudo Noise sequence random generator based optical transmitter is controlled using heat sink profile and airflow. Heat sink and airflow are the cooling techniques for thermal efficient design on FPGA.

In optical communication systems PN sequences is interrupted by many parameters such as chromatic dispersion [5], chromatic dispersion in time domain [5], chromatic dispersion in frequency domain [6]. Fig. 1 shows, the design for our PN generator for optical transmitter using SSRG method which is less temperature sensitive then Fibonacci generator. Designed PN generator for optical transmitter using SSRG method is implemented on FPGA. In FPGAs the Vertex™ series-6 is use to configure 16-bit shift register with one Look up Table to generate the PN sequence [7]. Abstract—Junction temperature is the final temperature of any device, after that device became dead. In this paper, junction temperature of target device . Pseudo Noise sequence random generator based optical transmitter is controlled using heat sink profile and airflow. Heat sink and airflow are the cooling techniques for thermal efficient design on FPGA. We operated target device at high speed transceiver logic (HSTL) on FPGA at 1, 10,100 and 1000 (GHz) operating frequency. Each IO standard is examined with two airflow values (250 MFL and 500MFL) and Heat sink values (Low profile, Medium profile and high profile). For HSTL_I the reduction in junction temperature is (4%, 5%, 16% .
