U2896B is a modulation PLL for GSM, DCS and PCS systems. The device 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 a 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. Broadband operation provides high flexibility for multi-band frequency mappings. The IC is available in a shrinked small-outline 36-pin package (SSO36).
