The ODT-REF-SV1P8-12 is a high-performance reference current and voltage generator. The block incorporates a proprietary architecture to achieve high power supply rejection across an ultra-wide bandwidth, which is needed for high speed data converter applications. ODT-REF-SV1P8-12 does not need any calibration or programming. If values other than the defaults are needed, programming capability exists for all currents and voltages. Default mode for current generation requires a 5kW external precision resistor tied to a bump. The IP includes built-in calibration to automatically match an internal resistor to an external resistor. This calibration can be used in production test and applied to Non-Volatile Memory (NVM) outside the IP to allow for precise trimming of the IP. The ODT-REF-SV1P8-12 is powered by a 1.8V analog supply and a 0.8V digital supply.
