Description for the ADC12D1800RF
The 12-bit 1.8 GSPS ADC12D1800RF is an RF-sampling GSPS ADC that can directly sample input frequencies up to and above 2.7 GHz. The ADC12D1800RF augments the very large Nyquist zone of TI’s GSPS ADCs with excellent noise and linearity performance at RF frequencies, extending its usable range beyond the 3rd Nyquist zone.
The ADC12D1800RF 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 lead-free 292-ball thermally enhanced BGA package over the rated industrial temperature range of –40°C to +85°C.
