SX1781 PLL Frequency Synthesizer with Integrated VCO ADVANCED COMMUNICATIONS & SENSING FINAL DATASHEET GENERAL DESCRIPTION The SX1781 is a high-performance low phase noise integer-N frequency synthesizer for wireless communications applications. The circuit embeds a fully integrated PLL (including VCO tank and loop filter), complementary output buffers The divider and power-down settings are programmable via an SPI interface. A Lock Detector pin linked to a squelch function have been designed to ease the software development. PIN DIAGRAM FEATURES Frequency range:1200 to 1400 MHz Frequency step: 250 kHz min. Phase noise: -85 dBc/Hz @ 10 kHz offset Reference spurs: -67 dBc Hopping time: 350 µs max. Operating voltage: 3.0 - 3.
