Clock fanout for LVDS, LVPECL, and PECL lines
The Texas Instruments DS90LV110TMTC/NOPB is a 1:10 fanout buffer that accepts LVDS, LVPECL, or PECL inputs and delivers ten LVDS outputs. The differential input and output path (Yes/Yes per the spec) preserves signal integrity across the fanout tree. This part sits in the clock distribution chain of telecom line cards, data-acquisition backplanes, and any system that needs to split a high-speed reference clock to multiple ASICs or FPGAs without degrading edge rates.
The 400 MHz maximum frequency covers most LVDS clock distribution up to gigabit-class serial links (e.g., 1 GbE, SFP+ reference clocks). If your design needs to fan out a 312.5 MHz or 156.25 MHz oscillator to ten destinations, this buffer has the bandwidth. The 1:10 ratio means one device replaces two 1:5 or three 1:4 buffers, consolidating BOM count and routing complexity. However, the ten outputs present a combined load that the upstream clock source must drive — check the input capacitance and drive strength of the preceding PLL or oscillator.
Supply and temperature — 3.3V rail, industrial range
The 3V to 3.6V supply range ties this part to a 3.3V rail. If your board runs 2.5V or 5V clock logic, you will need a local regulator or a different buffer. The 28-TSSOP package (0.173" body width, 4.40 mm) is a fine-pitch surface-mount footprint that routes well on standard PCB stacks.
The NOPB suffix confirms lead-free construction — no Pb in the solder finish. For new designs, there is no imminent obsolescence risk.
