2 / 24 page  1999 Dec 14 2 Philips Semiconductors Product specification QPSK transmitter TDA8050 FEATURES • Programmable gain • PLL controlled carrier frequency • 3-wire transmission bus • 5 V supply voltage. APPLICATIONS • QPSK modulation. GENERAL DESCRIPTION The Quadrature Phase Shift Keying (QPSK) transmitter is a monolithic bipolar IC dedicated for quadrature modulation of the I and Q signals. It includes: • Two double-balanced mixers • Symmetrical Voltage Controlled Oscillator (VCO) with 0 to 90 degree signal generation for modulation • Phase-Locked Loop (PLL) for IF frequency control • Conversion mixer • PLL for RF frequency control • Gain controlled output amplifier • 3-wire bus and an output buffer. Two PLLs are incorporated, the first PLL includes: • Fixed main divider • Crystal oscillator and its programmable reference divider • Phase/frequency detector combined with a fixed charge pump. The second PLL includes: • Divide-by-four preamplifier • 12-bit programmable divider • Crystal oscillator and its programmable reference divider • Phase/frequency detector combined with a ‘clever’ charge pump which drives the tuning amplifier, including 9 V output.
