12-Bit, 3.2/2.0 GSPS RF Sampling ADC
1.0 General Description
The 12-bit 3.2/2.0 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 3^rd
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.
