The M21418 and M21428 are high-speed, low-power, low-jitter cable drivers. They are designed to drive serial
digital video data through 75  coaxial cable typically used in SMPTE and DVB-ASI video applications. The
M21428 cable driver is optimized for performance from 143 Mbps up to 2970 Mbps, the M21418 cable driver is
optimized for performance from 143 Mbps up to 1485 Mbps. Both the M21428 and M21418 have selectable slew
rates for SD-SDI and HD-SDI applications.
The typical output rise/fall time of the M21428 is 100 ps for HD and 3G rates, the typical output rise/fall time of the
M21418 is 100 ps for HD rates. All devices have 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 M21418
and M21428 are pin compatible. The M21418/M21428 support a maximum single ended output swing of 1600
mVp–p, when configured appropriately.
All devices are packaged in a new high performance 3x3 mm MLF package to simplify the PCB and reduce
package parasitics with resulting improvements in Output Return Loss (ORL). Both devices are available in an
RoHS compliant package, that is backwards compatible with standard JEDEC SnPb processes.

Features
1.1.1
HD-SDI and SD-SDI Slew-rate Selection
The output slew rate of the M21418 and M21428 are selectable to conform with the different SD-SDI and HD-SDI
specifications, in the case of the M21428 this includes 3G-SDI. With SD/HD = Low, rise/fall time is typically 100 ps.
The slew rate will vary depending on the output matching network and connector used.
With SD/HD = High, for standard definition (143 to 540 Mbps) applications, the rise/fall time is typically 600 ps,
which is compliant with SMPE 259M and SMPTE 344M.
1.1.2
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 ±10% which meets SMPTE requirements. The output amplitude can
also be adjusted to range from 500 to 1600 mVPP single ended using the following formula:
Output Swing = (600/RSET) [RSET in k] (in mVPP, Single Ended)
The actual swing is set as a function of the IC supply voltage, the external termination voltage and the limitations
are shown in Table 1-1. For a 3.3 V minimum termination voltage, the IC can be SMPTE compliant for all supply
voltages. In applications where lossy matching or splitting networks are used, the M21418/M21428 offers
additional gain of up to 1600 mVPP swings. When using swings in excess of 1200 mV, there will be an increase in
rise and fall times.

High-speed Inputs
Rev V6
The M21418/M21428 are designed to be operated with input signals as low as 100 mV or up to 2000 mV
differential peak to peak. The M21418/M21428 uses external 50  input termination resistors to match 100 
differential impedance transmission lines for improved system level performance. The M21418/M21428
recommended input circuits are shown in Figure 1-1.
Note that AC-coupling is not required when the M21418/M21428 are driven by MACOM Broadcast video devices.

High-speed Outputs
The M21418/M21428 output buffer is an open collector buffer that is designed for a return loss of 15 dB at SD and
HD rates and 10 dB at 3G rates, using standard through-hole BNC connectors as typically employed in broadcast
video equipment. A typical output matching circuit is shown in Figure 1-3. The Output Return Loss (ORL) is
dependent on many factors such as the value and type of components used, PCB layout, PCB trace lengths, and
type of PCB di-electric, therefore, the recommendations in the figure below should be used as starting guidelines
only. Different output matching network topologies and different component values will result in different ORL
performance.
The M21418/M21428 has SD-SDI and HD-SDI rise/fall times that are typically faster than the legacy cable driver
devices but within the relevant SMPTE specification for additional margin in most designs. The faster output slew
rate results in a more open eye. The actual maximum output of the part depends on the applied IC voltage as well
as the external termination voltage for the load termination. The limitations are discussed in Section 1.1.

Manufactureability
The values shown in this section may change; however, these are standard requirements.
2.6.1
Electrostatic Discharge
Tested per JESD22-A114. This device passes 2000 V of ESD Human Body Model (HBM) testing.
Tested per JESD22-C101. This device passes 500 V of ESD Charged Device Model (CDM) testing.
Tested per EIA/JESD78. This device passes 150 mA of trigger current at 85 °C during Latchup testing.
2.6.2
Peak Reflow Temperature
M21418/M21428G (RoHS compliant package): Peak reflow temperature is 260 °C per JEDEC standards.

Design Considerations
See Digital Video Interfacing Application Note (212xx-APP-001-A) for guidance on the following:
•
Component Placement and Layout
•
Routing Considerations and Thermal Considerations
The M21418/M21428 consumes less power than legacy devices, therefore the M21418/M21428 will contribute
less thermal energy resulting in a lower operating temperature.
