Fully integrated serial-link receiver with optical interface for long-haul display interconnects

We report a fully integrated serial-link receiver with optical interface fabricated with a 0.18 μm complementary metal oxide semiconductor technology for long-haul display interconnects. The receiver includes a trans-impedance amplifier, a limiting amplifier, a clock and data recovery circuit, 1:64 de-multiplexer and a built-in error checker. The receiver produces 64-bit wide electrical signals from photodetector output signals produced by 5.28, 5.6 or 6.25 Gb/s optical signals delivered through up to 700-m multi-mode fibre. It can support serialised data for Ultra eXtended Graphics Array (UXGA), 1080 p and Wide Ultra eXtended Graphics Array (WUXGA). The receiver core occupies 0.59 mm² with 42.4 mW power dissipation at 6.25 Gb/s bit rate from a 1.8 V supply.
