M21328 HD/SD and 2xHD-SDI Cable Driver The M21328 is a high-speed, low-power, low-jitter cable drivers. It is designed to drive serial digital video data through 75 coaxial cable typically used in SMPTE and DVB-ASI video applications. The M21328 cable driver is optimized for performance from 143 Mbps up to 2970 Mbps. It has selectable slew rates for SD-SDI and HD-SDI applications. The typical output rise/fall time of the M21328 is 100 ps for HD and 2xHD rates. It has a typical set slew rate of 600 ps at SD rates. The default output voltage swing is compliant with SMPTE 292M, 259M, 344M and 424M using a 750 1% resistor. The M21328 supports a maximum single ended output swing of 1600 mVpp, when configured appropriately. The M21328 device is packaged in a new high performance 4x4 mm MLF package to simplify the PCB and reduce package parasitics with resulting improvements in Output Return Loss (ORL). It is available in an RoHS compliant package, that is backwards compatible with standard JEDEC SnPb processes. The M21328 is pin compatible with the GS2978. It will also fit the footprint of the GS1578/1578A, but with the added feature of an Output Disable control pin.
