ICS874003AG-04LF

Overview

The ICS874003AG-04LF is a PCI Express jitter attenuator and fanout buffer from the FemtoClock series, manufactured by Renesas Electronics Corporation. It features a single PLL circuit with a 1:3 input-to-output ratio, converting differential inputs to differential LVDS outputs. The device supports maximum frequencies up to 320MHz and accepts various input types including HCSL, LVDS, LVHSTL, LVPECL, and SSTL. It operates on a supply voltage of 3.135V to 3.465V within an ambient temperature range of 0°C to 70°C. The component is housed in a 20-TSSOP surface-mount package.
