1.0 Functional Description
1.1 General Nomenclature
Through out this data sheet, physical pins will be denoted in BOLD print.
1.2 Features
1.2.1 HD-SDI and SD-SDI Slew-rate Selection
The output slew rate of the M21218 is selectable to conform with the different SD-SDI and HD-SDI specifications. 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.
1.2.2 Output Amplitude Adjustment
For SMPTE compliance, an external 750Ω ±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 kΩ] (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 1-1. For a 2.5V 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 1-1. Output Swing vs. Supply and Termination Voltage AVDD (V) AVDDTERM (V)* Maximum Swing (Single-ended mVp–p) Minimum Swing (Single-ended mVp–p) 2.5–3.3V 3.3V 1200 mV 500 mV 2.5–3.3V 5.0V 1600 mV 500 mV * ±5% tolerance allowed for AVDDTERM.

1.3 Pin Definitions
1.3.1 High-speed Inputs
The M21208/M21218 are designed to be operated with input signals as low as 100 mV or up to 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 and 1-2.

1.3.2 High-speed Outputs
The M21208/M21218 output buffer is an open collector buffer that is designed for typical return loss of 15dB using standard through-hole BNC connectors as typically employed with the GS9068/GS1528 series recommended back-termination and matching circuit as shown in Figure 1-3. 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 1-3.
