JAJSPK6B December 2015 – January 2023 ADS54J66
PRODUCTION DATA
The ADS54J66 is a low-power, wide-bandwidth, 14-bit, 500-MSPS, quad-channel, telecom receiver device. The ADS54J66 supports the JESD204B serial interface with data rates up to 10 Gbps supporting one lane per channel. The buffered analog input provides uniform input impedance across a wide frequency range and minimizes sample-and-hold glitch energy. The ADS54J66 provides excellent spurious-free dynamic range (SFDR) over a large input frequency range with very low power consumption. The device digital block includes a 2x and 4x decimation low-pass filter with fS / 4 and k × fS / 16 mixers to support a receive bandwidth up to 200 MHz for use as a Digital Pre-Distortion (DPD) observation receiver.
The JESD204B interface reduces the number of interface lines allowing high system integration density. An internal phase locked loop (PLL) multiplies the incoming ADC sampling clock to derive the bit clock which is used to serialize the 14-bit data from each channel.
