testing, pattern generation, memory testing,
and logic vector capture. This family features
maximum clock rates of 10, 25, or 50 MHz; selectable voltage levels
compatible with 2.5, 3.3, and 5 V TTL logic; and individually configured
pins for input or output. With both synchronous and asynchronous timing
modes, handshaking, and a software API designed around the NI-DAQmx
driver, NI 6535/36/37 devices have the flexibility to meet the requirements
of semiconductor, consumer electronics, and communications applications.
Applications
Digital Interfacing
• Use NI 6535/36/37 devices to interface digital systems and devices
directly with PC-based applications
• Control, communicate with, or send data to a digital device or system
• Analyze and record digital data
• Perform bidirectional communications with handshaking
Timing Modes
• Pattern I/O or sample clock (synchronous) – transfer
patterns using an internal or external clock signal
• Burst handshaking (synchronous) – handshake an NI 6535,
NI 6536, or NI 6537 device and the peripheral device during
synchronous transfer to maximize the transfer rate
• Handshaking I/O (asynchronous) – transfer patterns when both the
NI 6535, NI 6536, or NI 6537 device and the peripheral device are ready
• On-demand (unstrobed or static I/O) – acquire or generate
data through software-timed commands
• Change detection – acquire data whenever a change
occurs on one or more digital lines
Low-Cost, Selectable-Voltage, Digital I/O Devices up to 50 MHz
High Signal Quality
NI 6535/36/37 devices feature an improved architecture, offering not
only higher clock rates up to 50 MHz at low cost but also superior signal
integrity and impedance matching.

Improved Architecture Compatible with NI 6533
and NI 6534 Applications
These devices are ideal replacements for future-proofing applications
currently using NI 6533/34 devices.
• NI 6535/36/37 devices are software-compatible with existing
NI 6533/34 NI-DAQmx applications
• You can interface to existing NI 6533/34 fixtures and terminal blocks
with the NI 653x cable adapter
• NI 6535/36/37 devices are compatible with most NI 6533/34
timing modes – pattern I/O, handshaking, change detection, and burst

Connectivity Options
To meet connectivity requirements for high-speed digital applications,
you can use NI 6535/36/37 devices with a variety of accessories.
• A CB-2162 connector block
• A 50
Ω
shielded flying lead cable
• A VHDCI high-density connector
High-Speed Data Streaming
• Generate and acquire larger digital waveforms with PCI Express
high-speed devices, using the ideal, low-cost NI 6535/36/37 devices
• Stream continuously at up to 200 MB/s of data
• Stream data from the host computer’s memory or high-end storage
solution such as NI RAID arrays and controllers
• Use for applications requiring high speeds and fast streaming
capabilities such as LCD testing, wireless protocols, ADC/DAC
interfacing, or digital pattern capture
• Visit
ni.com/streaming

Multidevice Synchronization
Figure 2. You can use NI 6535/36/37 devices with an NI 653x cable adapter to connect to
existing NI 6533/34 applications.
• In comparison to legacy digital I/O boards, NI 6535/36/37 devices
have improved signal quality. In Figure 3, the top eye diagram is from
an NI PXIe-6535 generating at 10 MHz. The bottom diagram shows an
NI PXI-6534 generating a 10 MHz signal using signal termination
recommended by NI.
These products use the PXI trigger bus or RTSI bus to send and receive
clock and trigger signals to and from other NI 6535/36/37 devices in your
system. With these capabilities, you can create synchronized systems
with large numbers of digital I/O lines.
