Product Summary

The TDA6060XS is a video-modulator. The TDA6060XS IC combines a digitally programmable phase locked loop (PLL) with a multi-standard video modulator and programmable sound FM and AM modulator. This highly integrated chip allows for simpler design and lower system cost and compatibility with all world standards, including PAL, NTSC and SECAM. TDA6060XS offers designers maximum flexibility with an on-board PLL that permits the tuning process, gain settings and status with I2C bus microprocessor control. The frequency of the TDA6060XS can be set precisely from 30 MHz to 950 MHz in increments of 250 kHz. The frequency range VHF Low, VHF High, Hyper band and UHF can be changed with different tank circuit applications.

Features

TDA6060XS features: (1)a digitally programmable I2C bus controlled phase locked loop(PLL) controlled; (2)I2C bus interface with fast mode (400 kHz) possible; (3)Up to four PLL I2C bus addresses selectable by the DC voltage applied at the Chip Address Selection (CAS) pin (pin 5); (4)a LC tuned frequency and amplitude-stable balanced multivibrator oscillator for the VHF Low, VHF High, Hyperband and UHF range tuned with different LC tank circuits; (5)a software gain adjustable video amplifier; (6)Clamped video input with peak white level detection for I2C readable overload amplifier status to determine needed I2C bus controlled gain setting of the video amplifier; (7)a double balanced mixer with a double balanced output for the RF modulator; (8)a sound modulator for FM or AM modulation; (9)a programmable sound carrier oscillator with no external LC tank for all four worldwide frequencies (4.5, 5.5, 6.0 and 6.5 MHz); (10)second sound carrier input for Nicam or second FM carrier applications; (11)high current output switch port which could be used for RF source input selection; (12)a 5 level A/D convertor; (13)test mode including a test pattern generator.
