ASIC Engineering Analog Design Leader | high-speed optical transceiver circuits (modulator drivers, TIAs, CDRs, PLLs, ADC/DAC) | 10+ years

Design and develop mixed-signal ASIC circuitry for Cisco’s next-generation silicon photonics optical transceiver modules, spanning receive and transmit datapaths. Own full-chip electrical specifications, create verification test plans, and author designs for modulator drivers, serializers, PLLs, TIAs, and control circuits. Debug bring-up and lab validation issues to improve yield and failure analysis while coordinating across electrical, optical, digital, SI/PI, and product teams.
