EVAL-CN0243-EB1Z, High Dynamic Range RF Transmitter Signal Chain Evaluation Board Using Single External Frequency Reference for DAC Sample Clock and IQ Modulator LO Generation

説明

• EVAL-CN0243-EB1Z, Evaluation Board for Interfacing the ADL670x family of IQ modulators with integrated PLL to the AD9122 dual LVDS DAC and AD9516 clock generator. CN-0243 Circuit is ADRF6702 IQ Modulator with Internal LO Synthesizer, Synthesizer IQ Modulator Interface The ADRF6702 IQ modulator is a unique device in several respects. In addition to its exceptional dynamic range, it also includes a fractional-N PLL, which allows programming of discrete LO frequency steps of less than 25-kHz while at the same time keeping the overall frequency multiplication small enough to avoid a large increase in phase noise from the reference to the synthesizer output
