DC1369A-E

The DC1369A-E from Analog Devices Inc. is an evaluation kit featuring 14-bit analog-to-digital converters (ADCs) such as the LTC2258-14, LTC2257-14, and LTC2256-14. These ADCs are engineered for digitizing high-frequency, wide dynamic range signals, making them suitable for demanding communications applications.

The evaluation kit showcases the AC performance of the ADCs, including a typical Signal-to-Noise Ratio (SNR) of 74dB and a Spurious Free Dynamic Range (SFDR) of 88dB. The ultralow jitter of 0.17psRMS allows for effective undersampling of IF frequencies. DC specifications include a typical Integral Non-Linearity (INL) of ±1LSB and Differential Non-Linearity (DNL) of ±0.3LSB, with no missing codes over temperature. The transition noise is a low 1.13LSBRMS.

Digital outputs can be configured as full rate CMOS, double data rate CMOS, or double data rate LVDS. A separate output power supply enables the CMOS output swing to range from 1.2V to 1.8V. The ENC+ and ENC? inputs support differential or single-ended drive with various signal types including sine wave, PECL, LVDS, TTL, or CMOS. An optional clock duty cycle stabilizer is included to maintain high performance across a wide range of clock duty cycles.

This evaluation kit is ideal for applications in communications, cellular base stations, software-defined radios, portable medical imaging, multi-channel data acquisition, and nondestructive testing.
