They are designed to drive serial digital video data through 75 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 750 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.

With SD/HD = Low, the high-definition (1485 Mbps) slew rate is typically 100 ps. The slew rate will vary depending on the output matching network and BNC connector used. With SD/HD = High, for standard definition (143 to 540 Mbps) applications, the slew rate is typically 600 ps, which is compliant with SMPTE 259M and SMPTE 344M. The M21208 has no control over slew rate; this is set at the SD requirement. 2.2.2 Output Amplitude Adjustment For SMPTE compliance, an external 750 1% resistor at RSET to AVDD is recommended for a swing level of 800 mV within a tolerance that is less than 7%. The output amplitude can also be adjusted to range from 500 to 1600 mV using the following formula: Output Swing = (600 / RSET) mVp-p [RSET in k] (in mVpp, single-ended) The actual swing is set as a function of the IC supply voltage and external termination voltage as shown in Table 2-1. For a 3.3V minimum termination voltage, the IC can be SMPTE compliant for all supply voltages. In applications where a lossy matching or splitting networks are used, the M21208/M21218 offers additional gain for up to 1600 mV output swings, so the output after the lossy network can be SMPTE compliant. For single-supply 3.3V operation, the swing range is compatible with the GS9068/GS9068A and GS1528/1528A. Table 2-1.

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 2-1 and 2-2.

The Output Return Loss (ORL) may be further optimized by using a different output matching network or component values and may vary with PCB layout or component selection. The output return loss of the M21208/M21218 is measured while forcing the outputs to a DC 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. To estimate the output return loss performance under typical operating conditions, an interpolation can be performed on the measured values for the output high condition and output low condition. The equations used for the interpolation are as follows: RcH = RmH - (RmH - RmL) / 4 and RcL = RmL + (RmH - RmL) / 4 RcH = Corrected ORL with output high RcL = Corrected ORL with output low RmH = Measured ORL with output stuck high RmL = Measured ORL with output stuck low Figure 2-3.
