Preliminary speciﬁcation

Stand-alone OSD

PCA8516

FEATURES

• Display RAM: 256 × 13 bits

• Display character fonts: 253 (fixed in ROM, mask

programmable)

• Starting position of the first character displayed:

64 vertical and 64 horizontal starting positions can be

selected by software

• Character size: 4 different character sizes on a

line-by-line basis (1 dot = 1H/1V; 2H/2V; 3H/3V and

4H/4V)

• Character matrix: 12 × 18 with no spacing between

characters and no rounding function

• Foreground colours: 16 combinations of Red, Green,

Blue and Intensity on character-by-character basis

• Background/shadowing modes: 4 modes available, No

background, Box shadowing, North-West shadowing

and Frame shadowing (raster blanking) on frame basis

• Background colours: 16 combinations of Red, Green,

Blue and Intensity on word-by-word basis. Available

when background mode is in either the Box shadowing,

North-West shadowing or Frame shadowing mode

• OSD oscillator: on-chip Phase-Locked Loop (PLL)

• Character blinking ratio: 1 : 1, 1 : 3 and 3 : 1

(programmable frequency of 1

⁄16, 1⁄32, 1⁄64 or 1⁄128 of

fVSYNC) on character basis

• Display format: flexible display format by using the

Carriage Return Code, maximum number of characters

per line is also flexible and depends upon the OSD clock

frequency

• Spacing between lines: 4 choices comprising 0, 4, 8 and

12 horizontal scan lines

• Display character RAM address auto-post-increment

when writing data

• Fast I2C-bus serial interface (400 kbaud) or High-speed

3-wire serial interface (1 Mbaud) for data/command

transfer

• ACM (Active Character Monitor) specifically for use in

camcorder applications on word basis; can also be used

as a 5th colour control with R, G, B and I signals

• Programmable active input polarity of HSYNC and

VSYNC

• Programmable output polarity of R, G, B, I and FB

• Supply voltage: 5 V ±10%

• Operating temperature: −20 to +70 °C

• Package: SDIP24 or SO24.

GENERAL DESCRIPTION

The PCA8516 is a member of the PCA85XX CMOS family

and is an on-screen character display generator controlled

by a microcontroller via the on-chip fast I2C-bus interface

or the on-chip High-speed 3-wire serial interface. It is

suitable for use in high-end TV or camrecorder

applications and has also been designed for use in

conventional mid-end TV with advanced graphic features.
