Monolithic Linear IC
LA76070
NTSC Color Television IC
Overview
The LA76070 is an NTSC color television IC. In addition to providing IIC bus control based rationalization of IC control and the adjustment manufacturing process associated with the TV tube itself, it also includes all functions actually required in mass-produced television sets. As such, it is an extremely practical bus control IC.
* The LA7840/41 or LA7845N/46N is recommended as the vertical output IC for use with this product.

LA76070 Deflection Block - Input Signals and Measurement Conditions Unless otherwise indicated, set up the following conditions for each of the following measurements. 1. VIF and SIF blocks: No signal 2. C input: No signal 3. SYNC input: Horizontal and vertical composite synchronizing signal (40 IRE and other conditions, such as timing, must conform to the FCC broadcast standards.) Caution: The burst and chrominance signals must not be below the pedestal level.
4. Bus control conditions: All conditions set to the initial conditions unless otherwise specified. 5. The delay between the rise of the horizontal output (the pin 23 output) and the rise of the F.B.P IN (the pin 24 input) must be 9 s. 6. Unless otherwise specified, pin 25 (the X-ray protection circuit input) must be connected to ground. Caution: Perform the following operation if horizontal pulse output has stopped. 1. The bus data T_ENABLE bit must be temporarily set to 0 and then set to 1. (If the X-ray protection circuit operates, an IC internal latch circuit will be set. To reset that latch circuit, the T_ENABLE bit must be temporarily set to 0, even if there is no horizontal output signal being output.) Notes on Video Muting If horizontal pulse output has stopped, perform the operation described in item 1. above and then set the video mute bit set to 0. (This is because the video mute bit is forcibly set to the mute setting when the T_ENABLE bit is set to 0 or when the Xray protection circuit operates. This also applies when power is first applied.)
