It accepts one LVCMOS input and delivers one LVCMOS output at up to 108 MHz, with a 1:1 input-to-output ratio and no differential signalling on either side. The supply range is 3 V to 3.6 V, which means it runs cleanly off a standard 3.3 V rail but won't tolerate 2.5 V or 5 V without a regulator. Rated for the industrial temperature range of -40°C to 85°C, it fits outdoor telecom, factory automation, and motor-drive control boards that stay inside a cabinet. ## 108 MHz max — what it means for clock-tree margin The 108 MHz maximum frequency is the headline rating. In a typical clock-tree application you'd run it below that to leave margin for jitter and temperature drift — 80 to 90 MHz is a comfortable operating zone. Because it's a non-differential buffer (LVCMOS in, LVCMOS out), trace length matching matters less than it would for a LVPECL or LVDS fanout, but the single-ended output still needs a clean ground plane and a series termination resistor close to the pin to keep reflections off the clock line. ## Sourcing and lifecycle — active, no EOL worry The CDCS503PWR carries an Active lifecycle status and is ROHS3 compliant. For a BOM line that needs a reliable clock buffer for new designs, this part doesn't carry the obsolescence risk that older clock-family parts do.","metaTitle":"CDCS503PWR Clock Buffer/Multiplier, 108 MHz, 8-TSSOP","metaDescription":"TI CDCS503PWR LVCMOS clock buffer/multiplier, 108 MHz max, 3V-3.6V supply, -40 to 85°C, 8-TSSOP.
