5V9352PFGI

The 5V9352 is a low-skew, low-jitter, phase-lock loop (PLL) clock driver targeted for high performance clock tree applications. It uses a PLL to precisely align, in both frequency and phase. The 5V9352 operates at 2.5V and 3.3V. FUNCTIONAL BLOCK DIAGRAM DESCRIPTION: The 5V9352 features three banks of individually configurable outputs. The banks are configured with five, four, and two outputs. The internal divide circuitry allows for output frequency ratios of 1:1, 2:1, 3:1, and 3:2:1. The output frequency relationship is controlled by the fSEL frequency control pins. The fSEL pins, as well as other inputs, are LVCMOS/LVTTL compatible inputs Unlike many products containing PLLs, the 5V9352 does not require external RC networks. The loop filter for the PLL is included on-chip, minimizing component count, board space, and cost. Because it is based on PLL circuitry, the 5V9352 requires a stabilization time to achieve phase lock of the feedback signal to the reference signal. This stabilization time is required, following power up and application of a fixed-frequency, fixed-phase signal at REFCLK, as well as following any changes to the PLL reference or feedback signals. The PLL can be bypassed for test purposes by setting the PLL_EN to high. The 5V9352 is available in Industrial temperature range (-40°C to +85°C).
