ADC3441IRTQ25 (TEXAS INSTRUMENTS)

The ADC3441IRTQ25 is a quad-channel, 14bit analogue to digital converter in 56 pin VQFN package. The device is designed specifically to support demanding, high input frequency signals with large dynamic range requirements. An input clock divider allows more flexibility for system clock architecture design while the SYSREF input enables complete system synchronization. It supports serial LVDS interface in order to reduce the number of interface lines, thus allowing for high system integration density. The serial LVDS interface is two-wire, where each ADC data are serialized and output over two LVDS pairs. An internal phase locked loop (PLL) multiplies the incoming ADC sampling clock to derive the bit clock that is used to serialize the 14bit output data from each channel. In addition to the serial data streams, the frame and bit clocks are also transmitted as LVDS outputs. It is used in multi-carrier, multi-mode cellular base stations, munitions guidance, radar and smart antenna arrays.
