EVM Operational Procedure

Table 1-1. Three Pin Jumper List Table

JUMPER	FUNCTION	LOCATION: PINS 1–2	LOCATION: PINS 2–3	DEFAULT
SJP3	Provides AIN+ source to ADC	Source provided from T2	Source provided from Diff Amp	1–2
	device
SJP4	Provides AIN– source to ADC	Source provided from Diff Amp	Source provided from T2	2-3
	device

2.Connect supplies to the EVM as follows:

+5 V (4.75 V–5.25 V) ADC analog supply to J3 and return to J2.

+3.3 V (3 V–3.6 V) digital buffer supply to J4 and J1 and return to J6

3.Switch power supplies on.

4.Use a function generator with 50-Ωoutput to input a 105-MHz, 0-V offset, 1-Vrms sine-wave signal into J5. The frequency of the clock must be within the specification for the device speed grade.

5.Supply an input signal by using a frequency generator with a 50-Ωoutput to provide a 15.5 MHz, 0-V offset, –1-dBFS amplitude sine-wave signal into J11. A full-scale input tone into the ADC device is a differential 2.2 Vpp and dBFS can be calculated by using the following formula:

*dBFS + 20 log captured max code * captured min code , where N is the number of bits. 2N

6.The digital pattern on the output connector J9 should now represent a 2'scompliment sine wave and can be monitored using a logic analyzer.
