Description
The SP9050L is an integrated circuit (IC) chip designed for video graphics array (VGA) clock generation. It is capable of producing different output frequencies under firmware control, and is compatible with IBM PC/XT/AT and Personal System/2 computers. The SP9050L is specifically designed to work with Western Digital Imaging Video Graphics Array and 8514/A devices to optimize video subsystem performance.
Specifications and features
- Specified for dual voltage operation (VDD=3.3V or 5V), but operates continuously from 3.0V to 5.25V
- Designed to be powered-down for extended battery life
- Backward compatibility to the ICS90C64 and ICS90C63
- Dual Clock generator for the IBM-compatible Western Digital Imaging Video Graphics Array (VGA) LSI devices, and 8514/A chip sets
- Integral loop filter components, reduce cost and phase jitter
- Generates fifteen video clock frequencies (including 25.175 and 28.322 MHz) derived from a 14.318 MHz system clock reference frequency
- On-chip generation of eight memory clock frequencies
- Video clock is selectable among the 15 internally generated clocks and one external clock
- CMOS technology
- Available in 20-pin PLCC, SOIC, and DIP packages
Application Scenarios
The SP9050L is widely used in electronic devices that require VGA clock generation. It is commonly found in computer motherboards, graphics cards, and video display devices. It is also used in applications where a stable and accurate video clock signal is required for optimal performance.
