U2893B Datasheet (TEMIC Semiconductors) - Modulation PLL for GSM/ DCS and PCS Systems

U2893B, Modulation PLL for GSM/ DCS and PCS Systems

The U2893B is a monolithic integrated circuit.

It is realized using TEMIC’s advanced silicon bipolar UHF5S technology.

The device integrates a mixer, an I/Q modulator, a phase-frequency detector (PFD) with two synchronous-programmable dividers, and a charge pump.

The U2893B is designed for cellular
