Abstract This paper presents the design and the test results of a 25 Gbps VCSEL driving ASIC fabricated in a 55 nm CMOS technology as an attempt for the future very high-speed optical links. The VCSEL driving ASIC is composed of an input equalizer stage, a pre-driver stage and a novel output driver stage. To achieve high bandwidth, the pre-driver stage combines the inductor-shared peaking structure and the active-feedback technique. A novel output driver stage uses the pseudo differential CML driver structure and the adjustable FFE pre-emphasis technique to improve the bandwidth. This VCSEL driver has been integrated in a customized optical module with a VCSEL array. Both the electrical function and optical performance have been fully evaluated. The output optical eye diagram has passed the eye mask test at the data rate of 25 Gbps. The peak-to-peak jitter of 25 Gbps optical eye is 19.5 ps and the RMS jitter is 2.9 ps.

System On A Chip

The system in a package (SiP) including of a system on a chip (SoC) and a double-data-rate-three synchronous dynamic random access memory (DDR3 SDRAM) were studied with respect to the high-speed characteristics. The SiP was the multi-chip-module thin-profile fine-pitch ball grid array (MCM TFBGA) package with four-layer substrate. The high-speed 1600-Mbps data rate DDR3 signals were used in the signal integrity (SI) analysis. The SiP with low-cost silver (Ag) wires displayed a 500.18-ps aperture width in the eye diagram, which was successfully achieved signal integrity (SI) performance requirement. This work demonstrated the SiP with the Ag wires was the great potential solution for the advanced high-speed product applications.

AbstractIn this paper, performance analysis of high-speed superdense wavelength-division-multiplexing (SDWDM) optical add–drop multiplexer (OADM) optical ring network for 6 nodes, 45 wavelengths having channel spacing of 0.2 nm on 300 km unidirectional nonlinear single-mode fiber ring of 10 Gbit/s has been reported. The performance optimization of the system by comparing different modulation formats has been reported on the basis of eye diagram and bit error rate (BER). It has been reported that CSRZ modulation format can achieve BER as better as e-24, which gives best performance. This paper also presents a study of performance degradation caused by the crosstalk and the effect of channel spacing on SWDM system.
