PCB8517 Overview
plastic dual in-line package; 16 leads (300 mil) GENERAL DESCRIPTION PCB8517 The PCB8517 is a stand-alone OSD which is used to display the adjustment/status information on the screen of an auto-sync monitor for menu driving application. The display operation of the device is controlled by a microcontroller which programs the internal 273 bytes of RAM via a 3-wire high-speed serial interface.
PCB8517 Key Features
- 3-wire high speed (maximum 2.5 Mbits/s) serial interface with three types of transmission sequence. On-Screen Display (O
- On-chip PLL oscillator to generate the OSD dot clock frequency which is 384 × horizontal sync frequency
- Horizontal sync frequency range of 10 to 100 kHz
- 10 rows of 24 characters display buffer
- 128 character fonts
- 12 × 16 character matrix
- Programmable height of displayed character (from 16 to 63 scan-lines); frame basis
- 4 types of character size; single/double character height/width; row basis
- Horizontal starting position: 32 different positions (6 dots for each step)
- Vertical starting position: 64 different positions (4 scan-lines for each step)
