SDA9251-2X Datasheet 868352-bit Dynamic Sequential ACcess Memory For Television Applications (tv-sam)

Manufacturer: Siemens Semiconductor Group (now Infineon)

Overview: 868352-Bit Dynamic Sequential Access Memory for Television Applications (TV-SAM) SDA 9251-2X Preliminary.

General Description

The SDA 9251 is a triple port 868 352 bit dynamic sequential-access memory for high-data-rate video applications.

It is organized as 212 rows by 64 columns by 16 arrays by 4 bit to allow for the storage of 4-bit planes of a TV field (NTSC, PAL, SECAM, MAC) in standard or studio quality (13.5-MHz basic sample rate) or 4-bit planes of parts of a HDTV field.

The memory is fabricated using the same CMOS technology used for 1-Mbit standard dynamic random access memories.
