310Msps 14-bit A/D converter designed for digitizing high
frequency, wide dynamic range signals. It is perfect for
demanding communications applications with AC performance that includes 68.8dB SNR and 88dB spurious
free dynamic range (SFDR). The 1.25GHz input bandwidth
allows the ADC to undersample high frequencies with
good performance. The latency is only six clock cycles. n DC specs include ±1.2LSB INL (typ), ±0.35LSB DNL (typ)
and no missing codes over temperature. The transition
noise is 2.11LSBRMS.
The digital outputs are double data rate (DDR) LVDS. APPLICATIONS n n n n The ENC+ and ENC– inputs can be driven differentially with
a sine wave, PECL, LVDS, TTL, or CMOS inputs. An optional …
