Overview
The ADS54J66IRMP is a low-power, wide-bandwidth, 14-bit, 500-MSPS, quad-channel analog-to-digital converter (ADC) designed by Texas Instruments. This telecom receiver device is optimized for high-performance applications requiring low power consumption and high system integration density. The ADS54J66IRMP supports a JESD204B serial interface with data rates up to 10 Gbps per lane, facilitating efficient data transfer. The device features buffered analog inputs that provide uniform input impedance across a wide frequency range, minimizing sample-and-hold glitch energy. It also includes digital signal processing blocks with complex mixers and low-pass filters, supporting up to 200-MHz receive bandwidth.
