Xiamen UX High-Speed IC Co., LTD (UX) already successfully enter mass production of 155Mbps, 1.25Gbps Transimpedance Amplifier (TIA), Limiting Amplifier (LA), and Laser Diode Driver (LDD). All of these products adopt CMOS technique, which has many advantages like low cost, low power consumption, high good product rate and high performance/price ratio .The performance of these chips has completely meet or exceeded the level of the same kind of advanced products in the world, and they are pin-to-pin compatible with them. So you only need to build one kind of PCB for both 155M and 1.25G module if you adopt our products. 
    All of the 155 M and 1.25 G chips can work at both 3.3 V and 5 V power supply, and satisfy industrial standard of -45℃ ~85℃ temperature range, also the chip products meet RoHS laws requirement.
    We can provide the whole application plan for customers, even including PCB design for them to help them enter mass production as soon as possible.
