SBAS664B ­ MAY 2014 ­ REVISED NOVEMBER 2014 ADC34J4x Quad-Channel, 14-Bit, 50-MSPS to 160-MSPS, Analog-to-Digital Converter with a JESD204B Interface
1 Features 1 3 Description
The ADC34J4x is a high-linearity, ultra-low power, quad-channel, 14-bit, 50-MSPS to 160-MSPS, analog-to-digital converter (ADC). The devices are designed specifically to support demanding, high input frequency signals with large dynamic range requirements. A clock input divider allows more flexibility for system clock architecture design while the SYSREF input enables complete system synchronization. The ADC34J4x family supports serial current-mode logic (CML) and JESD204B interfaces in order to reduce the number of interface lines, thus allowing high system integration density. The JESD204B interface is a serial interface, where the data of each ADC are serialized and output over only one differential pair. An internal phase-locked loop (PLL) multiplies the incoming ADC sampling clock by 20 to derive the bit clock that is used to serialize the 14-bit data from each channel. The ADC34J4x devices support subclass 1 with interface speeds up to 3.2 Gbps. Device Information(1)
