Oki Electric Industry MSM514212
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. It has separate 8-bit-wide serial input and serial output ports that use independent data clocks to support asynchronous read and write operations.| Part No. | MSM514212 |

DESCRIPTION
The OKI High-reliability and low-power consumption are accomplished by using CMOS dynamic memory cells. 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.FEATURES
