Features - Serial bus interface control - Low power consumption in all operating modes - Image reject upconverter replaces external RF SAW filter - Transmit power control with 90 d B dynamic range - Variable gain RF block for improved in-band SNR - VHF VCO (external tank), 200 to 700 MHz - VHF VCO switching to increase the talk time of the radio - Two separate PLL synthesizers provide dual-loop, multi-band operation and power-save mode for both standby and lower frequency of operation Data Shee VCC_MIXER_1 VCC_MIXER_2 VGA_OUT+ VGA_OUT- VGA_CTRL - Transmit puncture pin disables programmable portions of device - RFLGA™ (40-pin, 6 x 6 x 1 mm) package with downset paddle VCC_IF Q+ Q- 1 2 3 4 5 6 7 8 9 10 11 32 31 30 29 28 27 26 25 24 23 22 21 POT_CELL - Fully programmable PLL dividers and selectable charge pump . currents for multi-VCO applications IF_IN+ IF_IN- N/C N/C N/C N/C N/C VCC_BIAS_DIFF_DRV CDMA_DRV_OUT VCC_CDMA_DRV TX_PUNCTURE DATA LATCH_ENABLE CLK Description The SKY74702 device is a single-supply, monolithic integrated circuit. It is designed for use in single-mode Code Division Multiple Access (CDMA) cellular voice/data applications including extensions for CDMA-Japan. The SKY74702 is a highly integrated superheterodyne transmitter that incorporates the following ponents: - In-Phase and Quadrature (I/Q) modulator - accepts the analog I and Q current outputs from the baseband analog processor and converts them to Intermediate Frequency (IF) signals - Voltage Controlled Oscillator (VCO) and VHF synthesizer - generates the LO signal for the quadrature modulator - UHF...
