TEMIC U2896B Manuals

The U2896B is a modulation PLL for GSM, DCS, and PCS systems. It is realized using TEMIC's advanced silicon bipolar UHF5S technology and integrates a mixer, an I/Q modulator, a phase-frequency detector (PFD) with two synchronous programmable dividers, and a charge pump. The U2896B is designed for cellular phones such as GSM900, DCS1800, and PCS1900, applying transmitter architecture at which the VCO operates at the TX output frequency. No duplexer is needed since the out-of-band noise is very low. The U2896B exhibits low power consumption and broadband operation for high flexibility in multi-band frequency mappings. The IC is available in a shrinked small-outline 36-pin package (SSO36).
