The Texas Instruments LMH0307GRE/NOPB is a 3 Gbps HD/SD SDI dual output driver designed for professional video equipment. It supports both DVB-ASI and SMPTE standards, making it suitable for broadcast infrastructure, video routers, and production switchers that need to drive serial digital video over coax cable. The GPIO control interface lets the system select output modes without an external serial bus.
The supply range is tighter than a typical 3.3 V ±10% rail. The 3.14 V to 3.47 V window means the design needs a regulated 3.3 V supply with at least ±5% accuracy. A standard 3.3 V LDO or DC-DC with 2% tolerance will hold the rail inside this band across load and temperature, but a 3.3 V rail that droops to 3.0 V under transient load will violate the minimum and risk signal degradation on the SDI output.
25-CSBGA package — layout and assembly considerations
The 25-CSBGA (3x3 mm) package is a fine-pitch BGA. The 0.5 mm ball pitch requires a controlled impedance PCB stackup and microvia or via-in-pad for the inner balls. The small footprint saves board area but demands careful solder paste stencil design and X-ray inspection. The supplier device package is 25-CSBGA (3x3), not a larger BGA variant — verify the land pattern against the TI application note for this package code.
