Description

The PAN-IC is an add-on IC to be used, for example, between analog-to-digital conversion and a serial (field) memory. The SAA4995WP performs the following tasks:
· Linear horizontal sample rate conversion in both zoom and compress direction, with a sample rate conversion factor between 0.5 and 2
· Dynamic sample rate conversion for panorama mode display of e.g. 4 : 3 material on a 16 : 9 display
· Dynamic sample rate conversion for amaronap mode display of e.g. 16 : 9 material on a 4 : 3 display.

The PAN-IC SAA4995WP has the ability to increase the data rate from the ADC to a maximum of twice the data rate at the output. To achieve this a clock rate at twice the normal output clock rate is needed to write data to the memory.

All actions to generate a lower data rate, produces disable cycles in Write Enable (WE).
