BR9068FPJ is a low-power frequency synthesizer (PLL) product. Combined with an external loop filter and an external reference clock, BR9068FPJ can implement fractional-N or integer-N phase-locked loop (PLL) frequency synthesizer functionality. This product typically operates with a supply current of 47 mA at 1.8 V and 15 mA at 2.5 V. Compared to the BR9179 product, it consumes slightly more power while optimizing phase noise performance at offsets ≥100 kHz from the carrier, making it equally suitable for low-power application scenarios.
BR9068FPJ integrates a voltage-controlled oscillator (VCO) with a fundamental output frequency range of 1.62 GHz to 3.24 GHz. Through 1/2/4/8/16/32/64 frequency division circuits, it can generate RF output frequencies as low as 25.5 MHz. All on-chip registers are controlled via a standard serial peripheral interface.
