Hot-selling and scarce 8T33FS6221EPGI8 Low Voltage 1:20 Differential PECL/HSTL Clock Fanout Buffer QFP spot stock

Product Descriptions

The 8T33FS6221 is a bipolar monolithic differential clock fanout  buffer. Designed for most demanding clock distribution systems, the  8T33FS6221 supports various applications that require the  distribution of precisely aligned differential clock signals. Using SiGe  technology and a fully differential architecture, the device offers very  low skew outputs and superior digital signal characteristics. Target  applications for this clock driver is high performance clock  distribution in computing, networking and telecommunication  systems.

The 8T33FS6221 is designed for low skew clock distribution  systems and supports clock frequencies up to 2GHz. The device  accepts two clock sources. The CLK0 input can be driven by PECL  compatible signals, the CLK1 input accepts HSTL compatible  signals. The selected input signal is distributed to 20 identical,  differential PECL outputs. If VBB is connected to the nCLK0 or  nCLK1 input and bypassed to GND by a 10nF capacitor, the  8T33FS6221 can be driven by single-ended PECL signals utilizing  the VBB bias voltage output.

In order to meet the tight skew specification of the device, both  outputs of a differential output pair should be terminated, even if only  one output is used. In the case where not all ten outputs are used,  the output pairs on the same package side as the parts being used  on that side should be terminated.

The 8T33FS6221 can be operated from a single 3.3V or 2.5V supply.
