SDA9254-2 Datasheet 2.6 Mbit Dynamic Sequential ACcess Memory For Television Applications (tv-sam) With On-chip Noise Reduction Filter

Manufacturer: Siemens Semiconductor Group (now Infineon)

Overview: 2.6 MBit Dynamic Sequential Access Memory for Television Applications (TV-SAM) with On-chip Noise Reduction Filter Preliminary.

General Description

General The SDA 9254-2 is a bination of the TV-SAM SDA 9253 and an adaptive recursive filter to achieve a reduction of noise for video signals.

To get a closed loop one of the two output ports of the triple port memory is connected internally to the noise reduction filter.

External access to this port is not possible.
