The MAX1123 is a monolithic 10-bit, 210Msps analog-to-digital converter (ADC) optimized for outstanding dynamic performance at high IF frequencies up to 500MHz. The product operates with conversion rates of up to 210Msps while consuming only 460mW.At 210Msps and an input frequency of 100MHz, the MAX1123 achieves a spurious-free dynamic range (SFDR) of 74.5dBc. Its excellent signal-to-noise ratio (SNR) of 57.4dB at 10MHz remains flat (within 1.5dB) for input tones up to 500MHz. This makes the MAX1123 ideal for wideband applications such as digital predistortion in cellular base-station transceiver systems.The MAX1123 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 420MHz. 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 MAX1123 is available in a 68-pin QFN with exposed pad (EP) and is specified over the industrial (-40°C to +85°C) temperature range.For pin-compatible, lower and higher speed versions of the MAX1123, refer to the MAX1122 (170Msps) and the MAX1124 (250Msps) data sheets. For a higher speed, pin-compatible 8-bit version of the MAX1123, refer to the MAX1121 data sheet.See a parametric table of the complete family of pin-compatible, 8-/10-/12-bit high-speed ADCs.ApplicationsCable-Head End SystemsCommunications Test EquipmentDigital Predistortion ReceiversRadar and Satellite Subsystems Antenna Array ProcessingWireless and Wired Broadband Communication
