With an external loop filter and reference clock, the BR9069FLJ implements fractional-N or integer-N PLL frequency synthesis. Typical supply current is 55 mA at 3.3 V and 65 mA at 1.2 V, making it ideal for low-power applications. The BR9069FLJ integrates a VCO with a fundamental tuning range of 3 GHz to 6 GHz. On-chip divide ratios of 1, 2, 4, 8, 16, 32, or 64 extend the RF output down to 47 MHz. All registers are programmed via a standard SPI interface, and the device operates from 3.3 V and 1.2 V supplies.
