Product Overview
Engineered for analog video overlay generation, the Myson MTV021N-25 provides character and graphics display capabilities for CRT computer monitors and legacy video gear. Built in a standard 16-pin dual in-line package, this controller incorporates an internal phase-locked loop and character ROM to project menus, frequency readouts, and status text directly onto RGB video lines.
Key Features
- 16-pin plastic dual in-line package (PDIP-16) with 0.300-inch row spacing
- Horizontal sync input frequency handling up to 130 kHz
- On-chip phase-locked loop (PLL) operating up to 96 MHz
- 15 rows by 30 columns character display format with 12 x 18 dot matrix
- 272 total characters and graphic font capacity in internal mask ROM
- 8-color selectable output control
- Serial host microcontroller communication interface
- Fast analog RGB video signal overlay outputs
Applications
- Bench technicians replacing failed OSD generator ICs on legacy CRT computer monitors and industrial displays
- Video arcade and retro gaming restoration shops repairing on-screen setup menus and diagnostic screens
- Electronics hobbyists overlaying text, telemetry, or sensor readings onto standard analog RGB or composite video signals
- Maintenance engineers servicing legacy test equipment with built-in video display readouts
Frequently Asked Questions
What host interface is used to control this IC?
The MTV021N-25 communicates with the host microcontroller using a serial data bus interface to load display data, control registers, and character addresses.
What package style does this chip use?
This unit is housed in a standard 16-pin plastic dual in-line package (PDIP-16) with 0.300-inch row spacing, suitable for through-hole soldering or standard 16-pin DIP sockets.
What condition are these pulled ICs in?
These are clean pulls recovered from decommissioned equipment. Pins are straight and body markings are legible. As visual inspection was conducted without live circuit testing, they are sold as-is for bench repair and restoration projects.
