844003BI-01

The 844003BI-01 is a 3 differential output LVDS synthesizer designed to generate Ethernet reference clock frequencies. 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_SELA[1:0], DIV_SELB[1:0]): 625MHz, 312.5MHz, 156.25MHz, and 125MHz. The 844003BI-01 has 2 output banks, Bank A with 1 differential LVDS output pair and Bank B with 2 differential LVDS output pairs.

The two banks have their own dedicated frequency select pins and can be independently set for the frequencies mentioned above. The 844003BI-01 uses our 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements. The 844003BI-01 is packaged in a small 24-pin TSSOP package.
