A 100Gbps Interface for 4k/8k UHDTV Signals

A“100Gbps Real Time Interface” has been developed specifically to transmit 4k and 8k UHDTV image formats. This 100Gbps interface can carry 8k/50P-60P/4:4:4/12bit or 8k/100P-120P/4:2:2/10bit image formats. The DC balance and clock recovery was secured by adopting the 8b/10b coding. A transmission distance of 2km the same as those of the HD/3G-SDI optical interfaces was achieved by adopting the 1.3um QSFP28 optical module. The QSFP optical module has evolved and treats the data as 4×28Gbps. This 100Gbps Interface can be the next generation Real Time Interface that can cover all the 4k and 8k signal formats defined by SMPTE ST 2048-1 and SMPTE ST 2036-1 as well as SMPTE ST 274 and SMPTE ST 296. It also maintains backward compatibility because its I/O supports HD/3G-SDI.
