This document is the specification sheet of SAA4952WP memory controller, including the features, performance indicators and application scenarios of the memory controller
The Philips SAA4952WP is an integrated circuit memory controller designed for high-end TV sets using 2f, techniques. It supports acquisition, display, and deflection phase-locked loops (PLLs) for scan conversion between 50/100 Hz and 60/120 Hz systems. The device operates in serial memory structures and supports progressive scan modes, including 50 Hz/1250 lines and 60 Hz/1050 lines, as well as interlaced modes for 625 and 525 lines. It is capable of handling acquisition frequencies of 12, 13.5, 16, and 18 MHz, with display frequencies of 27, 32, and 36 MHz.
