FEATURES Interface with microcontroller · 3-wire high speed (maximum 2.5 Mbits/s) serial interface with three types of transmission sequence. On-Screen Display (OSD) · 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) · 8 foreground character colours: selection of only 2 out of the 8 (outside the window) and 4 out of the of 8 (in the window) in the same row · 3 character shadowing modes: No shadow Shadowing Bordering shadow · 3 fully programmable background windows with overlapping capability and presetting priorities (for multi-level application). The window colour can be selected from 1 out of 8 · Half tone in background window supported · Single 5 V power supply · Available in DIP16 package. ORDERING INFORMATION TYPE NUMBER PCB8517P PACKAGE NAME DIP16 DESCRIPTION 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. The on-chip PLL oscillator and programmable character height are used to keep the same character size displayed on the screen in different display modes, VGA, SVGA and XGA for example. The OSD of the PCB8517 provides display buffers of 10 rows with 24 characters each. These display buffers can select from 128 customized character fonts (with 12 × 16 bit resolution) to be displayed. The characters displayed on the screen can be specified double height, double width, different colour and with/without shadowing. Three positional background windows are provided for multi-level application.
