TRF3762-E 具有集成 VCO 的低噪声整型 N PLL 频率合成器

TRF3762-E is a high performance, highly integrated frequency synthesizer, optimized for high performance applications. The device includes a low-noise, voltage-controlled oscillator (VCO) and an integer-N PLL. TRF3762-E integrates divide-by 1, 2, or 4 options for a more flexible output frequency range. The device is controlled through a 3-wire serial-programming-interface (SPI) interface. For power sensitive applications, the device can be powered down by the SPI interface or externally via CHIP_EN (pin 2).

The TRF3762-E offers the ability to reduce lock time when compared to the TRF3761-E device. The TRF3762-E was designed so that the external loop filter is the determining factor in the setting of lock time
