PLL1708DBQRG4

Clock Generators, PLLs, Frequency Synthesizers Overview

The PLL1708DBQRG4 is a 3.3-V dual PLL multi-clock generator manufactured by Texas Instruments. It integrates two independent phase-locked loops to generate multiple clock outputs from a single reference input. The device supports an input frequency of up to 36.87 MHz and provides a 1:6 input-to-output ratio. It operates within a supply voltage range of 2.7 V to 3.6 V and functions reliably across an industrial temperature range of -25°C to 85°C. The component is housed in a 20-pin SSOP package with a width of 3.90 mm, designed for surface-mount assembly.
