T he AD9059/PCB evaluation board provides an easy-to-use
analog/digital interface for the dual 8-bit, 60 MSPS ADC. T he
board includes typical hardware configurations for a variety of
high speed digitization evaluations. On-board components in-
clude the AD9059 (in the 28-pin SSOP package), optional ana-
log input buffer amplifiers, digital output latches, board timing
drivers, and configurable jumpers for ac coupling, dc coupling,
and power-down function testing. T he board is configured at
shipment for dc coupling using the AD9059’s internal reference.
For dc coupled analog input applications, amplifiers U3 and U4
are configured to operate as unity gain inverters with adjustable
offset for the analog input signals. For full-scale ADC drive
each analog input signal should be 1 V p-p into 50
referenced
to ground. Each amplifier offsets its analog signal by +VREF
(+2.5 V typical) to center the voltage for proper ADC input
drive. For dc coupled operation, connect E7 to E9 (analog in-
put A to R11), E14 to E13 (amplifier output to analog input A
of AD9059), E4 to E5 (analog input B to R10), and E11 to E10
(amplifier output to analog input B of AD9059) using the board
jumper connectors.
For ac coupled analog input applications, amplifiers U3 and U4
are removed from the analog signal paths. T he analog signals
are coupled through capacitors C11 and C12, each terminated
to the VREF voltage through separate 1 k
resistors (providing
bias current for the AD9059 analog inputs, AINA and AINB).
Analog input signals to the board should be 1 V p-p into 50
for full-scale ADC drive. For ac coupled operation, connect E7
to E8 (analog input A to C12 feedthrough capacitor), E13 to
E15 (C12 to R15 termination resistor for channel A), E4 to E6
(analog input B to C11 feedthrough capacitor), and E10 to E12
(C11 to R14 termination resistor for channel B) using the board
jumper connectors.
T he on-board reference voltage may be used to drive the ADC
or an external reference may be applied. T he standard configu-
ration employs the internal voltage reference without any exter-
nal connection requirements. An external voltage reference may
be applied at board connector input REF to overdrive the lim-
ited current output of the AD9059’s internal voltage reference.
T he external voltage reference should be +2.5 V typical.
T he power-down function of the AD9059 can be exercised
through a board jumper connection. Connect E2 to E1 (+5 V
to PWRDN) for power-down mode operation. For normal op-
eration, connect E3 to E1 (ground to PWRDN).
T he encode signal source should be T T L/CMOS compatible
and capable of driving a 50
termination. T he digital outputs
of the AD9059 are buffered through latches on the evaluation
board (U5 and U6) and are available for the user at connector
Pins 30–37 and Pins 22–29. Latch timing is derived from the
ADC ENCODE clock and a digital clocking signal is provided
for the board user at connector Pins 2 and 21.
