NOTES

1. TO USE PECL DRIVER (U8), SOLDER JP41 AND JP42 AND REMOVE TRANSFORMER T1.

2. IN TWO-PORT MODE, IF DATACLK/PLL_LOCK IS PROGRAMMED TO OUTPUT PIN 8, JP25

AND JP39 SHOULD BE SOLDERED. IF DATACLK/PLL_LOCK IS PROGRAMMED TO OUTPUT

PIN 53, JP46 AND JP47 SHOULD BE SOLDERED. FOR MORE INFORMATION, SEE THE

TWO-PORT DATA INPUT MODE SECTION.
