M21428 3G/HD/SD-SDI Dual-Output Cable Driver
> Product Overview
The M21428 is a high-speed, low-power, low-jitter cable driver, designed to drive serial digital video data through 75Ω
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 Mbp with a typical ryse/fall time of
100ps for HD-SDI and 3G-SDI.
The default output voltage swing in a SMPTE compliant 800mV when set by an external 750Ω ±1% resistor. The M21428
also has the option of providing a signal with double the output swing at 1600mV, which can be used in cascade applica-
tions.
The M21428 is provided in a green and RoHS compliant package.
