M21208/M21218
SD and HD/SD-SDI Digital Video Cable Drivers
The M21208 and M21218 are high-speed, low-power, low-jitter cable drivers. They are designed to drive serial
digital video data through 75Ω coaxial cable typically used in SMPTE and DVB-ASI video applications. The
M21218 cable driver is optimized for performance from 143 Mbps up to 1485 Mbps, it has selectable slew rate for
SD-SDI and HD-SDI applications. The M21208 cable driver is optimized for performance from 143 Mbps up to 540
Mbps with SD-SDI slew rates.
The typical output rise/fall time of the M21218 is 100 ps for HD rates. Both devices have a typical set slew rate of
600 ps at SD rates. The default output voltage swing is compliant with SMPTE 292M, 259M and 344M using a
750Ω ±1% resistor. The M21208 and M21218 are pin compatible, with the exception that the M21208 has no SD/
HD control pin. M21208/M21218 support a maximum single ended output swing of 1600 mVp–p, when configured
appropriately.
Both devices are available in a small outline RoHS compliant package, which is backwards compatible with
standard JEDEC SnPb processes. The M21208 is pin compatible with the GS9068/9068A devices, and the
M21218 is pin compatible with the GS1528/1528A, both support 2.5V and 3.3V operation.

... High-speed Inputs The M21208/M21218 are designed to be operated with input signals as low as 100 2000 mV differential peak to peak. The M21218 requires external termination resistors to minimize high-speed reflections. The M21208 and M21218 are designed as pin compatible replacements to the GS9068/9068A and GS1528/1528A cable drivers, respectively, and the recommended input circuits are shown in Figure 1-1 ...

... The output return loss of the M21208/M21218 is measured while forcing the outputs high or low state. Under normal operating conditions, the outputs of the M21208/M21218 will not be held to a static high or low state, so the measured output return loss will not represent the actual output return loss under normal operating conditions ...
