MODEL DESCRIPTIONS
The SYNTH1000 series of Direct Digital Synthesizer (DDS) boards contain two complete low noise
precision waveform synthesizers on a single PCIe bus card. Each channel's frequency may be
programmed from 50KHz to 800MHz (with reduced performance to 1000MHz). Amplitude may be
independently programmed from 0 to 800mV p p into 50 ohms. Designed for low jitter operation in
communications, industrial and scientific applications, these boards function in PCIe bus systems using
supplied drivers for 64 bit Windows 7™ or CentOs 6. In addition to dual synthesizers, the SYNTH1000x2
board has three external TTL inputs for each synthesizer channel, which can be used to allow external
equipment to dynamically switch each synthesizer between up to eight frequency profiles, for a variety of
dynamic waveform synthesis applications (frequency/phase/amplitude modulation, high speed quadrature
modulation, triggered frequency sweeping, etc.). The TTL inputs can also be used to switch ramping
direction, or pausing the ramp.
Both synthesizer channels are driven from a common 3.5GHz CRO timebase, frequency locked to a sub
1ppm accurate TCXO, for precise channel to channel frequency tracking.
All models have two independent output channels, each driven by the filtered output of a dedicated Analog
Devices AD9914 DDS IC, and include additional firmware to allow advanced functionality such as software
selectable internal or externally triggered profile switching capability. Further information for each model is
given below.
MODEL: SYNTH1000X2
Model Synth1000x2 is a Dual channel DDS board with two independent Direct Digital Synthesizers,
each separately programmable for any frequency between 50kHz and 800MHz, in increments of
approximately 0.816 Hz. The two channels may each be independently programmed for frequency,
amplitude and phase, or may be externally controlled via three TTL inputs (PS0 PS2) to dynamically
select up to eight frequency/phase profiles per synthesizer, via hardware control. The two synthesizer
outputs are conveniently provided by SMA output connectors.
MODEL: SYNTH1000X2SQRWAVE
Model Synth1000x2SQRWAVE is similar to the Synth1000x2 model, but instead output a 700mV peak
to peak square wave on each channel, instead of a sine wave. Unlike the sine wave outputs whose
frequency may be programmed from 50KHz to 800MHz (with reduced performance to 1000MHz), the
square wave outputs are limited to 1MHz to 1000MHz. All other functionality is equivalent.

PHYS CAL
SYNTH1000 boards are full size PCIe bus boards designed to be inserted into a PCIe x16 (physical)
slot, but only requires x8 PCIe connectivity. It also can be installed into PCIe x8 open ended PCIe
sockets, provided there is enough vertical room between boards. Due to the protrusion of its cooling
fan, the SYNTH1000 requires a blank slot between it and the neighboring board to its component side.
The figure below shows the locations of the SMA signal output and digital I/O connectors, and LED
indicators.
To avoid overheating, all SYNTH1000x2 boards must be installed a in well cooled workstation, PC or
server chassis.

HARDWARE ARCHITECTURE
SYNTH1000 series boards are comprised of a digital section and an analog section. The digital
section includes a high speed programmable logic device which implements the PCI interface and
embedded firmware for controlling the DDS cores of the analog section. The analog section contains a
3.5GHz low jitter clock, and two AD9914 single chip Direct Digital Synthesizer (DDS) ICs. The current
outputs of each DDS are fed, via a broadband RF transformer and a 900MHz low pass filter, to two
SMA jacks.
SYNTHES ZER A & B OUTPUTS (DDS A OUT, DDS B OUT)
The two analog synthesizer outputs are provided on SMA connectors with amplitude (nominally 0
450mV RMS into 50 ohms). The frequency, phase, amplitude, frequency sweep rate (if specified), and
other parameters are software programmable.
TTL0-TTL5 PROF LE SELECT NPUT L NES
The external TTL input pod is connected to the Synth1000x2 board via a 26 pin cable, and the
interface is used for external profile selection inputs in external profile mode and as ramping controls in
external ramp mode. TTL 0 2 control profiles for SynthA and TTL 3 5 control profiles for SynthB on the
board.
EXTERNAL REFERENCE CLOCK NPUT L NE
The SMA jack labeled GC_P on the external TTL input pod may be optionally used for an external
clock input, if desired. This external clock, which may be any frequency between 10 and 50MHz can
make it easier to sync multiple synth1000x2 devices together in a multi board system. The labview
interface currently supports a 10mhz external clock, if another frequency is required additional steps
are needed.
EXTERNAL RAMP MODE
The external TTL input pod can also function to control the sweep. External Ramp mode enables
hardware ramp direction change (on TTL 0,3 for synth A/B), hardware ramp pause (on TTL 1,4 for
synth A/B) and OSK (on TTL 2,5 for synth A/B, currently untested).

LED INDICATORS
There are seven Red/Green LEDs on the top edge of the SYNTH1000x2 board that are useful during
system integration for monitoring the board status. The functions of the LEDs are outlined below.
ENABLE ACQ LED (FREQUENCY LOCK NG ENABLED ND CATOR)
This LED displays whether the frequency locking loop is enabled.
Green: CRO (3.5GHz Coaxial Resonant Oscillator) is successfully locked to <1ppm TCXO reference or
external reference clock.
OFF: CRO is not successfully locked to a TCXO or external reference frequency. Usually this
condition occurs during warm up.
DMA LED
This LED indicates the FLL (Frequency Locking Loop) DAC has reached its low limit without locking.
This is an error condition.
Green: DAC at zero, tuning direction for lock is down.
OFF: DAC not at zero.
ACQU R NG LED
This LED indicates the FLL (Frequency Locking Loop) DAC has reached its high limit without locking.
This is an error condition.
Green: DAC at Full Scale, tuning direction for lock is up.
OFF: DAC not at Full Scale.
MODE LED
This LED displays whether the device is to be locked to internal clock or external clock.
Green: Set up to be locked to internal clock
Off: Set up to be locked to external clock
CLOCK BAD LED
This LED displays the current status of the 3.5GHz internal clock:
Off: Internal clock locked to high accuracy reference oscillator.
Red: Internal clock not locked correctly. This means one of three things:
1) Not Locked.
