General Description

The TRF2056 device 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 achieve rapid channel switching.

Two operating modes are available: 1) SA7025 emulation mode in which the device emulates the Philips SA7025 fractional-N synthesizer and 2) extended performance mode (EPM), which provides additional

Key Features

  • including fractional accumulator modulos from 1 to 16 (compared to only 5 or 8 for the SA7025 synthesizer). The TRF2056 device provides external loop filters and all functions necessary for voltage-controlled oscillator (VCO) control in a dual phase-locked loop (PLL) frequency synthesizer system. A main channel is provided for radio frequency (RF) channels and an auxiliary channel for intermediate frequency (IF) channels. The current-output charge pumps directly drive passive resistance-capacit.
