TRF2050 Datasheet (Texas Instruments) - LOW-VOLTAGE 1.2-GHz FRACTIONAL-N/INTEGER-N SYNTHESIZER

TRF2050, LOW-VOLTAGE 1.2-GHz FRACTIONAL-N/INTEGER-N SYNTHESIZER

The TRF2050 is a low-voltage, low-power consumption 1.2-GHz fractional-N/integer-N frequency synthesizer component for wireless applications.

Fractional-N division and an integral speed-up charge pump are used to achieve rapid channel switching.

Two operating modes are available: 1) SA7025 emulatio

TRF2050 Features

* including fractional accumulator modulos from 1 to 16 (compared to only 5 or 8 for the SA7025) and programmable control of the speed-up mode duration (compared to the SA7025 method of holding the strobe line high). Along with external loop filters, the TRF2050 provides all functions necessary for vo
