Part Name(s) : NTE849 NTE-Electronic
NTE Electronics
Description : Integrated CIRCUIT TV HORIZONTAL/Vertical Countdown Digital Sync System View

Description:
The NTE849 is an integrated CIRCUIT in a 14–Lead DIP type package designed for use in TV HORIZONTAL/ vetical countdown digital sync systems. In some video playback units, there are incorrect frequency relationships between HORIZONTAL and field frequencies. Automatic forced asynchronous mode eliminates jitter when equalizer pulses are correct, but these incorrect frequency relationships exist.

Features:
● Automatic Forced Asynchronous Mode to Remove Jitter
● Improved Low Voltage Start–Up Operation
● Lower Zero–State HORIZONTAL–Drive Pulse Output
● Improved Symmetry for HORIZONTAL–Drive Output
● Improved Automatic Standard Operation
● Noise Detector
● Handles Standard NTSC and Non–Standard Signals
● Automatic Mode Recognition
● Clock Input
● Vertical Ramp (Sawtooth) Generator
● Vertical Amplifier
● Vertical Blanking Generator
HORIZONTAL Drive Pulse Output
● Ratio–Voltage Regulator
● Inherent Interlace for NTSC Signals
● Vertical–Hold Control Eliminated
● Supply Voltage Range: 10.8V to 13.2V
● Rapid Pull–In
● Co–Channel Sync Lockout for NTSC Signals
● I2L Logic

Part Name(s) : LA7916 LA7916 SANYO
SANYO -> Panasonic
Description : Peripheral CIRCUIT for TV/VCR Frepuency SYNTHESIZER Channel Select System View

Overview
The LA7916 contains CPU/PLL-excluded peripheral CIRCUITs such as switch, +5V power supply (with RST), sync detector, low-pass filter for color TV/VCR frequency SYNTHESIZER channel select system use.

Features
• The band switch truth table can be changed in a short period of time at the user’s option.
• The band switch is of pnp output type which need not be driven externally.
• The operational amplifier for low-pass filter is excellent in pulse response because of its high-impedance input pin.

Functions
• Band switch (2-input 4-output).
• Video signal, flyback pulse, AFT output-used detection of tuning mode and HORIZONTAL sync mode.
• +5V power supply, with RST ouput (for CPU).
• Operational amplifier for low-pass filter (for frequency SYNTHESIZER).

Part Name(s) : NTE1739 NTE-Electronic
NTE Electronics
Description : Integrated CIRCUIT TV HORIZONTAL/Vertical Countdown Digital Sync System View

Description:
The NTE1739 is a video sync system in a 16–Lead DIP type package designed for use in television, monitor or video display products. The NTE1739 contains a HORIZONTAL phase–locked oscillator and vertical countdown. It also features composite blanking and burst–gate outputs which, when external ly summed, produce the sandcastle pulse necessary for the operation of most chroma/luma CIRCUITs. The NTE1739 is intended for use in 525–line systems and operates with standard or nonstandard input signals. An automatic mode–recognition CIRCUIT forces operation into the nonsynchronous mode for nonstandard sync input signals.

Features:
HORIZONTAL Oscillator
• Vertical Countdown
• Composite Blanking Output
• Burst–Gate Output
HORIZONTAL Ramp Generator
• Internal Shunt Regulator
