GENERAL DESCRIPTION The TSA6060 is a frequency synthesizer manufactured in SUBILO-N technology (components laterally separated by oxide). The device performs all the tuning functions of a PLL radio tuning system. The IC is designed for application in all types of radio receivers. FEATURES • On-chip AM and FM prescalers with high input sensitivity • On-chip high-performance one-input-two-output, tuning voltage amplifier for the AM and FM loop filters • On-chip two-level current amplifier (charge pump) for loop gain adjustment • One reference oscillator (4 or 8 MHz) for both AM and FM • High-speed tuning provided by a powerful digital memory phase detector • 40 kHz output reference frequency for communication between the FM/IF system and microcontroller-based tuning interface IC (TEA6100) • Oscillator frequency range of 500 kHz to 30 MHz and 30 MHz to 200 MHz • Four selectable reference frequencies: 1, 10, 25 or 50 kHz, for both tuning ranges • I2C-bus interface to a microcontroller • Software controlled band switch output • In-lock detector output. APPLICATIONS • FM mains and car radios • VHF receivers 30 to 200 MHz.
