We present the design and test results of a Drivers and Limiting AmplifierS ASIC operating at 10 Gb/s (DLAS10) and three miniature optical transmitter/ receiver/transceiver modules (MTx+, MRx+, and MTRx+) based on DLAS10. DLAS10 can drive two transmitter optical subassemblies (TOSAs) of vertical cavity surface emitting lasers (VCSELs), receive the signals from two receiver optical subassemblies (ROSAs) that have no embedded limiting amplifiers (LAs), or drive a VCSEL TOSA and receive the signal from a ROSA, respectively. Each channel of DLAS10 consists of an input continuous time linear equalizer (CTLE), a four-stage LA, and an output driver. The LA amplifies the signals of variable levels to a saturation amplitude of 800 mV (peak-peak). The output driver drives VCSELs or impedance-controlled traces. DLAS10 is fabricated in a 65-nm CMOS technology. The die is 1 mm \times1 mm. DLAS10 is packaged in a 4 mm \times 4 mm 24-pin quad-flat no-leads (QFNs) package. DLAS10 has been tested in MTx+, MRx+, and MTRx+ modules. Both measured optical and electrical eye diagrams pass the 10-Gb/s eye mask test. The input electrical sensitivity is 40 mVp-p, while the input optical sensitivity is -12 dBm. The total jitter of MRx+ is 29 ps (P-P) with a random jitter of 1.6 ps (rms) and a deterministic jitter of 9.9 ps. Each MTx+/MRx+ module consumes 82.6 and 174.4 mW/ch, respectively.
