The LTC2209 is a 160Msps 16-bit A/D converter designed for digitizing high frequency, wide dynamic range signals with input frequencies up to 700MHz. The input range of the ADC can be optimized with the PGA front end.
The LTC2209 is perfect for demanding communications applications, with AC performance that includes 77.3dBFS Noise Floor and 100dB spurious free dynamic range (SFDR). Ultra low jitter of 70fsRMS allows undersampling of high input frequencies with excellent noise performance. Maximum DC specs include ±5.5LSB INL, ±1LSB DNL (no missing codes).
The digital output can be either differential LVDS or single-ended CMOS. There are two format options for the CMOS outputs: a single bus running at the full data rate or demultiplexed busses running at half data rate. A separate output power supply allows the CMOS output swing to range from 0.5V to 3.6V.
The ENC+ and ENC– inputs may be driven differentially or single-ended with a sine wave, PECL, LVDS, TTL or CMOS inputs. An optional clock duty cycle stabilizer allows high performance at full speed with a wide range of clock duty cycles.

Evaluation Kits (4)
Demonstration circuit 1685A features the LTC6417, a 1.6GHz differential ADC buffer driving the LTC2209, a 16-bit 160Msps ADC. The DC1685B is supplied with a bandpass filter centered at 140MHz between the buffer and ADC. The filter center frequency can be changed to optimize performance at different analog input frequencies. Both single-ended and differential configurations are supported at the inputs. The DC1685A has been developed from the DC1281A, used to characterize LTC2209 family of ADCs.
Use the DC1685A with a DC890 FastDAACS and PScope™ Software to collect time and frequency data.
