Description

A serial link transmitter for CMOS image sensors in subatomic physics experiment is developed. It encodes 256-bit/10 MHz payload with two interleaved RS(31, 27) codes and transmits serialized data with a CML driver at 3.2 Gb/s data rate. With the RS codes, at most 4 symbols in the transmission could be corrected, corresponding to a 20-bit consecutive bits error. A charge-pump PLL generates 1.6 GHz clock for DDR operation from a 40 MHz reference. Pre-emphasis is employed in the transmitter, enabling serial data to be transmitted over low mass cables. Digital blocks are triplicated to resist SEU. The proposed transmitter has been fabricated in a 0.18 µm CMOS technology. A preliminary measurement gives a frame data rate of $3\cdot10^{-12}$ with a confidence level of 94.5$\%$, corresponding to a BER for the payload of $1.2\cdot10^{-12}$ with a confidence level of 94.9$\%$. The power consumption of the transmitter is 135 mW at a typical setting. It was irradiated to 4.5 Mrad($SiO_2$) and no functionality degrading is observed. SEU measurement will be carried out and reported in the conference.
