Renesas Electronics Corporation Clock/Timing - Application Specific IDTCV137PAG

The IDTCV137PAG is a programmable clock device designed specifically for AMD K8 processors, featuring a 56-pin configuration. It supports CPU output frequencies of up to 400MHz and includes multiple high precision phase-locked loops (PLLs) for various clock outputs, including CPU, SRC, and PCI Express. The device incorporates a band-gap referenced IREF to minimize the effects of VDD variations on differential outputs, enhancing system performance. Key specifications include cycle-to-cycle jitter of less than 85ps for CPU clocks and less than 100ps for SRC clocks. The IDTCV137PAG supports multiple spread spectrum modulation options, allowing for isolated adjustments without impacting other clock groups. It also features SMBus block read/write capabilities and selectable output strength for various clock outputs. The device is available in both SSOP and TSSOP packages, making it suitable for a range of applications requiring precise clock timing.
