NTE730 TV Video IF System QDIP-20
Info als pdf File
Description:
The NTE730 is a monolithic integrated circuit in a 20−Lead Quad−In−Line package that incorporates
an entire video TV−IF subsystem on a single chip. Innovations in integrated circuit design, in addition
to the many active devices and closely matched components utilized in the circuit, make the NTE730
ideally suited for use in color and black and white TV receivers.
The primary functions performed by the IF subsystem are video IF amplification, linear detection, video
output amplification, AGC from a keyed supply, AGC delay for tuner, sound carrier detection,
sound carrier amplification, and a buffered AFT output. The advanced circuit design of the NTE730
also includes secondary functions for improved noise immunity and minimal airplane flutter. An isolated
zener reference diode, incorporated in the IC, provides a conveninet and economical means
for controlling the regulated voltage supply. The inherent wide bandwidth capability (10−70MHz) and
high overall gain (87dB) make the NTE730 suitable for other AM IF applications whose frequencies
range within this bandwidth.
