Renesas Electronics 840002I
The 840002I is a 2 output LVCMOS/LVTTL Synthesizer optimized to generate Fibre Channel reference clock frequencies. The 840002I uses IDT’s 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Fibre Channel jitter requirements. The 840002I is packaged in a 16-pin TSSOP package.| Part No. | 840002I |
