PLL with integrated VCO for clock and frequency control
The Texas Instruments SN74LV4046ANS is a phase-lock loop (PLL) with an on-chip voltage-controlled oscillator (VCO), designed for frequency synthesis, clock recovery, and FM demodulation in systems that need a clean, locked clock derived from a reference input. Accepts CMOS and TTL input levels and drives CMOS or TTL loads. The 1:3 input-to-output ratio provides three PLL outputs from a single reference, useful for fanning out a clock to multiple loads on the same board.
38 MHz maximum frequency — what it means for your loop bandwidth
The PLL locks up to 38 MHz. The 1:3 input-to-output ratio can multiply the reference frequency by three.
Supply range: 3 V to 5.5 V covers both logic families
Rated from 3 V to 5.5 V.
Temperature grade: -40°C to 125°C for harsh environments
The industrial temperature range of -40°C to 125°C qualifies this PLL for harsh environments. Storage temperature exceeds the operating range — the part can survive brief excursions beyond 125°C during reflow or storage, but the 125°C ceiling is the running limit.
