Product Summary

The BA1604F-E2 is a tone decoder IC that enable the frequency to be selected in precise detail, using a PLL system. The BA1604F-E2 is configured of a PLL circuit, a detection circuit, a voltage comparator circuit and an output logic drive circuit. When the input signal is within the transmission range of the BA1604F-E2, PLL is synchronized (locked) to the input signal. At this point, the output voltage of the decoder drops, and the change turns on the transistors for the voltage comparator and output logic drive circuits. Applications are (1)Telephones; (2)Data communication systems; (3)Remote control systems.

Parametrics

BA1604F-E2 absolute maximum ratings: (1)VCC: 9V; (2)Pd: 350mW; (3)Topr: -10 to 75°C; (4)Tstg: -55 to 125°C.

Features

BA1604F-E2 features: (1)The detection bandwidth can be varied independently between 0 and 14%; (2)The output circuit can withstand a load current of up to 100mA, and is directly coupled to the logic circuit; (3)The center frequency offers a high level of stability; (4)High out-of-band signal and noise rejection capability; (5)Frequency can be changed over a range of 20 : 1 using an external resistor; (6)Compatible with EXAR XR-567 and Signetics NE567.
