They are perfect for demanding communications applications with AC performance that includes 70dB SNR and 90dB 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. DC specs include ±0.85LSB INL (typ), ±0.25LSB DNL (typ) and no missing codes over temperature. The transition noise is 1.82LSBRMS. APPLICATIONS The digital outputs are double-data rate (DDR) LVDS. nn The ENC+ and ENC– inputs can be driven differentially with a sine wave, PECL, LVDS, TTL, or CMOS inputs. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.
