Innovative design – 277mW total power at 125MSPS techniques are used to achieve high-dynamic • High Dynamic Performance: performance, while consuming extremely low power with 1.8V supply. This topology makes the ADS4245 – 88dBc SFDR at 170MHz well-suited for multi-carrier, wide-bandwidth – 71.4dBFS SNR at 170MHz communications applications. • Crosstalk: > 90dB at 185MHz The ADS4245 has gain options that can be used to • Programmable Gain up to 6dB for improve SFDR performance at lower full-scale input SNR/SFDR Trade-off ranges. These device includes a dc offset correction loop that can be used to cancel the ADC offset. Both • DC Offset Correction DDR (double data rate) LVDS and parallel CMOS • Output Interface Options: digital output interfaces are available in a compact – 1.8V parallel CMOS interface VQFN-64 PowerPAD™ package. – Double data rate (DDR) LVDS with The device includes internal references while the programmable swing: traditional reference pins and associated decoupling – Standard swing: 350mV capacitors have been eliminated. The ADS4245 is specified over the military temperature range (–55°C – Low swing: 200mV to 125°C). • Supports Low Input Clock Amplitude Down to 200mVPP Device Information • Supports Defense, Aerospace, and Medical ORDER NUMBER PACKAGE BODY SIZE Applications ADS4245MRGC25EP VQFN (64) 9mm × 9mm – Controlled Baseline – One Assembly and Test Site Block Diagram – One Fabrication Site – Available in Military (–55°C to 125°C) Temperature Range – Extended Product Life Cycle – Extended Product-Change Notification – Product Traceability 2 Applications • Wireless Communications Infrastructure • Software Defined Radio • Power Amplifier Linearization 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
