DESCRIPTION
The OKI MSM514212 is a high-performance serial-line memory. It is designed for use in NTSC,
PAL or SECAM Video line buffer applications such as digital comb filters in TVs/VTRs, IDTV
(Improved Definition Television), time based correction, or other applications that use serial
data including facsimiles, digital copy machines, etc. High-reliability and low-power consumption
are accomplished by using CMOS dynamic memory cells.
It has separate 8-bit-wide serial input and serial output ports that use independent data clocks
to support asynchronous read and write operations. Different clock rates are also supported that
allow alternate data rates between input and output data streams.
A wide range of variable delay bits (40 bits to 5,048 bits) are supported offering greater design
flexibility. Internal logic keeps all asynchronous accesses from being delayed by arbitrating the
data storage, and data retrieval requirements to provide maximum performance at all times.
All input and output signals are TTL compatible, and the MSM514212 is packaged in a standard
400 mil 28-pin plastic ZIP.
