12-Bit, 3.2/2.0 GSPS Ultra High-Speed ADC

1.0 General Description

The 12-bit 1.6/1.0 GSPS ADC12D1600/1000RF is an RF-

sampling GSPS ADC that can directly sample input frequen-

cies up to and above 2.7 GHz. The ADC12D1600/1000RF

augments the very large Nyquist zone of National’s GSPS

ADCs with excellent noise and linearity performance at RF

frequencies, extending its usable range beyond the 5

Nyquist zone

The ADC12D1600/1000RF provides a flexible LVDS inter-

face which has multiple SPI programmable options to facili-

tate 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 pack-

aged in a lead-free 292-ball thermally enhanced BGA pack-

age over the rated industrial temperature range of -40°C to

+85°C.
