12-Bit, 2.0/3.2 GSPS Ultra High-Speed ADC
1.0 General Description
The 12-bit, 2.0/3.2 GSPS ADC12D1000/1600 is the latest ad-
vance in National's Ultra High-Speed ADC family and builds
upon the features, architecture and functionality of the 10-bit
GHz family of ADCs.
The ADC12D1000/1600 provides a flexible LVDS interface
which has multiple SPI programmable options to facilitate
board design and FPGA/ASIC data capture. The LVDS out-
puts are compatible with IEEE 1596.3-1996 and support pro-
grammable common mode voltage.
The ADC12D1000/1600 is packaged in a leaded or lead-free
292-ball thermally enhanced BGA package over the rated in-
dustrial temperature range of -40°C to +85°C.
