345R-65LF

Clock Generators, PLLs, Frequency Synthesizers Overview

The ICS345R-65LF is a field-programmable clock synthesizer from the Renesas VersaClock family, manufactured by Integrated Circuit Specialties (ICS). It generates up to nine high-quality, high-frequency clock outputs from a single low-frequency crystal or clock input. The device operates with a maximum frequency of 200MHz and utilizes LVCMOS output logic. It features a 1:9 input-to-output ratio and accepts clock or crystal inputs without differential signaling. The component is housed in a 20-SSOP package and requires a supply voltage between 3.15V and 3.45V.
