1.3 Description
The 12-bit, 3.6 GSPS ADC12D1800 is the latest advance in TI's Ultra-High-Speed ADC family and builds
upon the features, architecture and functionality of the 10-bit GHz family of ADCs.
The ADC12D1800 provides a flexible LVDS interface which has multiple SPI programmable options to
facilitate board design and FPGA/ASIC data capture. The LVDS outputs are compatible with IEEE 1596.3-
1996 and supports programmable common mode voltage.
The product is packaged in a leaded or lead-free 292-ball thermally enhanced BGA package over the
rated industrial temperature range of –40°C to +85°C.
To achieve full rated performance for f_CLK > 1.6 GHz, write the maximum power settings one time
to Register 6h through the serial interface; see Section 5.6.1 for more information.
