The 840NT4-01I is clock generator designed to provide ethernet and USB clocks for Freescale B4/ T4-based systems. The 840NT4-01I utilizes Renesas' FemtoClock NG® PLL technology to synthesize eight low phase-jitter Ethernet reference clocks. The clock generator also provides a 24MHz USB reference clock and a 25MHz reference output.
