Type Ordering Code Package
TDA 6160-2X Q67000-A5085 P-DSO-28-1 (SMD)
Functional Description
Multistandard sound IF-device consisting of a mixer as a frequency converter, a voltage-controlled
oscillator (VCO) that can be continuously tuned in 10-kHz increments with crystal accuracy by
means of a PLL, and three following parallel FM-limiter amplifiers with coincidence demodulators.
The switching functions and setting of the PLL are controlled on an I2C bus.
Application
For use in satellite receivers.
