Quick Start Guide
Using the AD9514
By default the AD9514 is configured to provide a 180Mhz clock input to the AD9102 from a 1.44 Ghz sine wave
input to J10 of the EVB. The AD9514 has a configurable divider that can be set through external resistors on the
EVB. The AD9102 evaluation board allows the AD9514 divider to be set by changing resistors. Output 0 from the
AD9514 is used as a PECL output to drive the AD9102 CLKP/CLKN inputs. Output 2 is used to drive the external
clock on J9.
Table 2 summarizes a few common settings used to divide the input clock by 2, 4, 8 and 16.
