NTE7004
Integrated Circuit
Electronic Channel Select System Control
Description:
The NTE7004 contains CPU/PLL鈥揺xcluded peripheral circuits such as band switch, +5V power sup-
ply (with RST), sync detector, low鈥損ass filter for color TV/VCR frequency synthesizer channel select
system use.
Functions:
D
Band Switch (2鈥揑nput, 4鈥揙utput)
D
Video Signal, Flyback Pulse, AFT Output鈥揢sed Detection of Tuning Mode and Horizontal
Sync Mode
D
+5V Power Supply, with RST Output (for CPU)
D
OP Amp for Low鈥揚(yáng)ass Filter (for Frequency Synthesizer)
Features:
D
The Band Switch Truth Table can be changed in a short period of time at the user鈥檚 option.
D
The Band Switch is of PNP output type which need not be driven externally.
D
The OP Amp for Low鈥揚(yáng)ass Filter is excellant in pulse response because of it鈥檚 High鈥揑mped-
ance Input Pin.
