1.8v, 12-bit, 170msps Adc For Broadband Applications Integrated Products

The MAX1213 is a monolithic, 12-bit, 170Msps analog- to-digital converter (ADC) optimized for outstanding dynamic performance at high-IF frequencies up to 300MHz. The product operates with conversion rates up to 170Msps while consuming only 788mW. At 170Msps and an input frequency up to 250MHz, the MAX1213 achieves a spurious-free dynamic range (SFDR) of 72.9dBc. Its excellent signal-to-noise ratio (SNR) of 65.8dB at 10MHz remains flat (within 2dB) for input Tones up to 250MHz. This ADC yields an excellent low-noise floor of -68dBFS, which makes it ideal for wideband applications such as cable head-end receivers and power-amplifier predistortion in cellular base-station transceivers. The MAX1213 requires a single 1.8V supply. The Analog input is designed for either differential or single-ended operation and CAN be AC- or DC-coupled. The ADC also features a selectable on-chip divide-by-2 Clock circuit, which allows the user to apply Clock frequencies as high as 340MHz. This helps to reduce the phase noise of the input Clock source. A low-voltage differential signal (LVDS) sampling Clock is recommended for best perfor- mance. The converters digital outputs are LVDs com- patible and the data format CAN be selected to be either twos complement or offset binary. The MAX1213 is available in a 68-pin QFN package with exposed paddle (EP) and is specified over the industrial (-40C to +85C) temperature range. By Maxim Integrated Products
