8P791208 - Block Diagram
Description
The 8P791208 is a low additive jitter 2:8 buffer with CMOS / differential outputs. The device takes 1 or 2 reference clocks, selects between them, using a pin selection and generates up to 8 outputs that are the same as the reference frequency. The 8P791208 supports two output banks, each with its own power supply. All outputs in one bank generate the same output frequency, but each output can be individually controlled for output type or output enable. The device can operate over the -40°C to 85°C temperature range.
