MAX1122 - 170Msps Analog-to-Digital Converter

General Description

The MAX1122 is a monolithic 10-bit, 170Msps analogto-digital converter (ADC) optimized for outstanding dynamic performance at high IF frequencies up to 500MHz.

The product operates with conversion rates of up to 170Msps while consuming only 460mW.

Key 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 differential LVDS sampling clock is recommended for best performance. The converter’s digital outputs are LVDS compatible, and the data format can be selected to be either two’s complement or offset binary. The MAX1122 is available in a 68-pin QFN with exposed pad (EP) and is specified over the industrial (-40°C to +.

19-3027; Rev 2; 8/08 1.8V, 10-Bit, 170Msps Analog-to-Digital Converter with LVDS Outputs for Wideband Applications General Description The MAX1122 is a monolithic 10-bit, 170Msps analogto-digital converter (ADC) optimized for outstanding dynamic performance at high IF frequencies up to 500MHz. The product operates with conversion rates of up to 170Msps while consuming only 460mW. At 170Msps and an input frequency of 100MHz, the MAX1122 achieves a spurious-free dynamic range (SFDR) of 72dBc. Its excellent signal-to-noise ratio (SNR) of 57.5dB at 10MHz remains flat (within 1dB) for input tones up to 500MHz. This makes the MAX1122 ideal for wideband applications such as digital predistortion in cellular base-station transceiver systems. The MAX1122 requires a single 1.8V supply.
