LA7851 Details

OverviewThe LA7851 is a sync deflection circuit IC dedicated to CRT display use. It can be connected to the LA7832, 7833 (for vertical output use) to form a sync deflection circuit that meets every requirement for CRT display use.So far, ICs for color TV use have been applied to the sync deflection circuit for CRT display use and general-purpose ICs such as one-shot multivibrator, inverter and a lot of transistors have been used to form the peripherals such as sync input interface, horizontal phase shifter. The LA7851 contains these peripherals on chip, has a wide vertical pullin range of 20Hz, and adopts a stable circuit for horizontal oscillation from 15kHz to 100kHz aiming at improving the characteristics requierd for CRT display use.Features• The vertical pull-in range 20Hz permits non-adjusting at vertical sync 50Hz/60Hz.• The horizontal oscillation frequency can be adjusted stably from 15kHz to 100kHz.• The horizontal display can be shifted right/left.• The horizontal/vertical sync input can be used intact regardless of the difference in pulse polarity and pulse width.• The AFC feedback sawtooth wave can be obtained by simply applying a flyback pulse to the IC as a trigger pulse.• Any duty of the horizontal pulse can be set.• Good linearity because DC bias at vertical output stage is subject to sampling control within retrace time.On-Chip Functions[Horizontal Block] • AFC • Horizontal OSC • X-ray protector • Horizontal phase shift • AFC sawtooth wave generator • Horizontal pulse duty setting[Vertical Block] • Vertical OSC • Vertical sawtooth wave generator • Sampling type DC voltage control

Key Features

The vertical pull-in range 20Hz permits non-adjusting at vertical sync 50Hz/60Hz.
The horizontal oscillation frequency can be adjusted stably from 15kHz to 100kHz.
The horizontal display can be shifted right/left.
The horizontal/vertical sync input can be used intact regardless of the difference in pulse polarity and pulse width.
The AFC feedback sawtooth wave can be obtained by simply applying a flyback pulse to the IC as a trigger pulse.
Any duty of the horizontal pulse can be set.
Good linearity because DC bias at vertical output stage is subject to sampling control within retrace time.

FAQs

What is LA7851?

The LA7851 is a vertical deflection output IC (integrated circuit) designed for use in CRT (cathode-ray tube) television display systems. It is commonly used to drive the vertical deflection yoke and generate the vertical scanning waveform required to display images on a CRT monitor or TV.

How Does LA7851 Work?

The LA7851 works by receiving vertical deflection signals from the television's main chassis and amplifying and shaping those signals to drive the vertical deflection yoke. It generates the vertical sawtooth waveform necessary for drawing each frame of the image on the CRT screen. The IC's output drives the yoke, which in turn moves the electron beam vertically across the screen to create the visual display.

How Many Pins does LA7851 have and What are the Functions of the Pinout Configuration?

The LA7851 is housed in a 10-lead SIP (Single In-line Package) or DIP (Dual In-line Package). The pinout configuration includes:

1. N/C: No connection pin.
2. N/C: No connection pin.
3. Pump: Pump-up capacitor connection pin.
4. Pump: Pump-up capacitor connection pin.
5. Output: Vertical output pin.
6. Sawtooth: Sawtooth waveform output pin.
7. S-correction: S-correction input pin.
8. N/C: No connection pin.
9. GND: Ground pin.
10. VCC: Power supply pin.

What are the Pros and Cons of LA7851?

Pros:

Integrated Functionality: Combines vertical deflection functions into a single IC, reducing external component count.
Optimized for CRT Displays: Specifically designed for driving vertical deflection yokes in CRT-based television or monitor systems.

Cons:
