元器件交易网讯 3月17日消息，据外媒报道，集成设备技术公司（IDT）推出一系列RMS相位抖动小于0.7ps的可编程时钟发生器频率在12kHz至20MHz内。
该设备满足代PCI Express 1/2/3， USB 3.0，和1G/10G以太网的抖动要求。该5P49V5901时钟发生器有四个通用输出，不同的输出类型生成高达350MHz频率。该器件整合了四个差分或8个单端时钟发生器，可存储多达四个不同的配置设置。
四个通用输出中每一组可被配置为HCSL、LVPECL、LVDS或双LVCMOS输出。该设备在系统中运行时，驱动每对输出的小数分频器驱很容易通过I2C来编程。
该器件通过一个4×4mm24引脚的VFQFPN进行封装。（元器件交易网 白玉涛译）
以下为外文：
Integrated Device Technology has introduced a range of programmable clock generators with RMS phase jitter less than 0.7 picoseconds over the full 12kHz to 20MHz range.
As a result the devices meet the jitter requirements of PCI Express Gen 1/2/3, USB 3.0, and 1G/10G Ethernet.
The 5P49V5901 clock generator has four universal output pairs capable of producing independent frequencies up to 350MHz in various output types. The device consolidates four differential or eight single-ended clock generators, and can store up to four different configuration settings.
The four universal output pairs are each independently configurable as HCSL, LVPECL, LVDS, or dual LVCMOS outputs. The fractional output dividers driving each output pair are easily programmed via I2C while the device is operating in the system.
Operating power is less than 100mW core power.
The device is available in a 24-lead 4 x 4 mm VFQFPN package.
