Product data sheet Rev. 3 — 9 February 2011 19 of 43 NXP Semiconductors ADC1613D series Dual 16-bit ADC: serial JESD204A interface 11.2.3 Common-mode output voltage (VO(cm)) An 0.1 μF filter capacitor should be connected between the pins VCMA and VCMB and ground to ensure a low-noise common-mode output voltage. When AC-coupled, these pins can be used to set the common-mode reference for the analog inputs, for instance via a transformer middle point. 11.2.4 Biasing The common-mode input voltage, VI(cm), at the inputs to the sample-and-hold stage (pins INAM, INBM, INAP, and INBP) must be between 0.9 V and 2 V for optimal performance. 11.3 Clock input 11.3.1 Drive modes The ADC1613D can be driven differentially (LVPECL). It can also be driven by a single-ended LVCMOS signal connected to pin CLKP (pin CLKM should be connected to ground via a capacitor) or pin CLKM (pin CLKP should be connected to ground via a capacitor).
