870931ARI-01LF

Clock Generators, PLLs, Frequency Synthesizers Overview

The 870931ARI-01LF is an LVCMOS clock generator manufactured by Renesas Electronics, formerly IDT. It utilizes an internal phase-locked loop (PLL) for frequency multiplication and low-skew output locking without requiring external loop filter components. The device accepts a single-ended reference clock input and provides six single-ended clock outputs. Key electrical specifications include a maximum output frequency of 80 MHz for outputs Q0 through Q4, and 40 MHz for the Q/2 output. It features 5V tolerant inputs, LVCMOS interface levels, and an output drive capability of ±24 mA. The unit operates on a full 3.3V supply voltage within an ambient temperature range of -40°C to 85°C.
