It combines high Programmable Fine Gain for SNR/SFDR performance and low power consumption in a Trade-Off compact 32 QFN package. Using an internal high • Parallel CMOS and Double Data Rate (DDR) bandwidth sample and hold and a low jitter clock LVDS Output Options buffer helps to achieve high SNR and high SFDR even at high input frequencies. • Supports Sine, LVCMOS, LVPECL, LVDS Clock Inputs and Clock Amplitude Down to 400 mVPP It features coarse and fine gain options that are used to improve SFDR performance at lower full-scale • Clock Duty Cycle Stabilizer analog input ranges. • Internal Reference with Support for External Reference The digital data outputs are either parallel CMOS or DDR LVDS (Double Data Rate). Several features • No External Decoupling Required for exist to ease data capture such as — controls for References output clock position and output buffer drive strength, • Programmable Output Clock Position and and LVDS current and internal termination Drive Strength to Ease Data Capture programmability. • 3.3 V Analog and 1.8 V to 3.3 V Digital Supply The output interface type, gain, and other functions • 32-QFN Package (5 mm × 5 mm) are programmed using a 3-wire serial interface. Alternatively, some of these functions are configured • Pin Compatible 12-Bit Family (ADS612X) using dedicated parallel pins so that the device comes up in the desired state after power-up. • Wireless Communications Infrastructure ADS612X includes internal references, while eliminating the traditional reference pins and • Software Defined Radio associated external decoupling. External reference • Power Amplifier Linearization mode is also supported. • 802.16d/e The devices are specified over the industrial • Test and Measurement Instrumentation temperature range (–40 °C to 85°C). • High Definition Video • Medical Imaging • Radar Systems ADS612X Performance Summary ADS6125 ADS6124 ADS6123 ADS6122 Fin = 10 MHz (0 dB gain) 90 91 93 95 SFDR, dBc Fin = 170 MHz (3.5 dB gain) 78 82 83 84 Fin = 10 MHz (0 dB gain) 71.1 71.3 71.5 71.6 SINAD, dBFS Fin = 170 MHz (3.5 dB gain) 67.6 69.1 69.2 69.8 Power, mW 417 374 318 285 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
