Integrated Circuit
Phase Lock Loop (PLL) Stereo Decoder
(BTSC System)
Description:
The NTE7116 is a phase lock loop (PLL) stereo decoder in a 20鈥揕ead DIP type package designed
primarily for low cost stereo decoding in a low鈥搕o鈥搈edium鈥搇ine TV. The MUX input (Pin1) is a low
impedance current input, the gain of the input amplifier is therefore determined by the external resistor
R1. All characteristics are measured with R1 = 47k鈩? The de鈥揺mphasis of (L, R) and (L 鈥?R) can
be chosen by means of external capacitors and resistors. The supply voltage range of the device is
from 7V to 16V.
