(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.

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. Typical lock times for the TRF3762-E are less than 350ms (depending on the loop filter circuit). All other features of the TRF3762-E are identical to the TRF3761-E including superior phase noise and spurious output as well as the programming model and register mapping. The TRF3762-E is pin-to-pin compatible to the TRF3761-E.
