IDT2309-1DC8

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT2309-1DC8 is a 3.3V zero delay clock buffer manufactured by Renesas Electronics Corporation, originally designed by Integrated Device Technology. It operates within a frequency range of 10MHz to 133MHz and distributes one reference input to two banks of outputs (five in Bank A and four in Bank B). The device features an on-chip PLL that aligns the phase between the incoming clock and output clocks to achieve zero delay. It is packaged in a 16-pin SOIC format and supports commercial temperature operation from 0°C to +70°C.
