M35062-XXXSP
SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
DESCRIPTION
M35062-XXXSP is CATV screen display control IC which can display 40 (horizontal) × 17 (vertical). It has built-in SYRAM which can be used with character ROM. It uses a silicon gate CMOS process and M35062-XXXSP housed in a small 32-pin shrink DIP package. For M35062-001SP that is a standard ROM version of M35062-XXXSP, the character pattern is also mentioned.

Function
These input pins determine address and data of display control register and display data memory by 8-bit parallel. Hysteresis input is required.
When this input pin transitions from “H” to “L”, the device is reset. Built-in a pull-up resistor. Hysteresis input is required.
Digital power supply pin. This pin must be connected to +5 V.
Ground pin. This pin must be connected to 0 V.
This pin outputs the composite video signal. The output signal is 2 VP-P. In superimpose mode, this pin’s signal consists of the OSD signal combined with the input composite signal CVIN.
This input pin is used for controlling the “white” character color level of the OSD signal.
This input pin is used for controlling the “black” character color level of the OSD signal.
This pin inputs the external composite video signal. In superimpose mode, this pin’s signal consists of the OSD signal combined with the external composite video signal.
This pin inputs the external composite video signal. This pin inputs the clamped external video signal, sync-sep internal.
This input pin is used to determine the slice voltage for extracting the sync signals from the video composite signal.
This is filter output pin 1.
Analog power supply pin. This pin must be connected to +5 V.
This is filter output pin 2.
