843003AGI-01LFT Allgemeine Beschreibung

The 843003I-01 is a 3 differential output LVPECL Synthesizer designed to generate Ethernet reference clock frequencies and is a member of the family of high performance clock solutions from IDT. Using a 19.53125MHz or 25MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the settings of 4 frequency select pins (DIV_SEL[A1:A0], DIV_SEL[B1:B0]): 625MHz, 312.5MHz, 156.25MHz, and 125MHz. The 843003I-01 has 2 output banks, Bank A with 1 differential LVPECL output pair and Bank B with 2 differential LVPECL output pairs. The two banks have their own dedicated frequency select pins and can be independently set for the frequencies mentioned above. The 843003I-01 uses IDT's 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements. The 843003I-01 is packaged in a small 24-pin TSSOP package.
