Up Converter Mixer with Fractional-N Frequency Synthesizer and VCO
AK1575
1. Overview
AK1575 is the up-converter mixer with fractional-N frequency synthesizer and integrated VCO. AK1575 is targeted at the application that requires a high linearity performance in frequency conversion. The mixer block is comprised of the differential input and the differential output. Input frequency range is from 20MHz to 500MHz and output frequency range is from 690MHz to 4000MHz. The current consumption and the analog performance can be adjusted by a resistance connected to BIAS pin. The power supply
voltage of mixer covers 4.75 to 5.25V. The local signal output frequency range is from 262.5MHz to 4400MHz generated by internal VCO, synthesizer and divider. Not only a local signal is supplied to an internal mixer, but also can be taken to outside. A power supply
voltage range of VCO/synthesizer is 2.7V to 3.6V or 4.75V to 5.25V. The CPU interface is 24bit serial data and its
voltage is ranging from 2.7V to 5.25V
