The amplitude resolution for each input signal component is 8 bit, the maximum clock
frequency is 30 MHz. Consequently the SDA 9270 is dedicated for applications in high
quality digital video systems. The data input stages and the internal data multiplexer
operate with a special input clock (SCA). For applications in the Siemens MEGAVISION
System the SCA-clock is identical with the memory output clock.
