2.4 Applications
The SB-3642 PMC card’s rugged construction and ability to operate over the industrial
temperature range makes it ideal for use in mission computers and other embedded
systems. This device can be combined with carrier cards for use in VME or cPCI
control systems employing 33/66MHz bus. The card also provides an ideal solution for
encoder-based systems that will mate with Resolver inputs. The card is a valuable
addition to design and test teams involved with resolver simulation and positioning.
Resolvers are used in applications that include modern high performance industrial
and military position feedback and control systems. Typical motion feedback
applications include motor control, machine tool control, antenna control, robotics, and
process control systems.

2.5 Mechanical Design
The SB-3642is a Front-I/O air-cooled PCI Mezzanine Card (PMC) designed to meet
or exceed vibration requirements specified in VITA-47 for a class V2 in air-cooled
applications. The SB-3642card also features CCPMC (Conduction Cooled PMC)
thermal rails and connector “anti-fretting” mounting holes per VITA-20-2005.
The front panel I/O connector layout uses a 68-pin front panel connection. The board
has conduction rails that do not interfere with the front panel connector. The front
panel connector includes a metal backshell with fastening thumbscrews.
The SB-3642is designed to meet or exceed the humidity requirements of ANSI/VITA
47, and has been tested to withstand 95% humidity.
To operate within the specified -40 to +85°C operating temperature, supplemental air
cooling of 300 LFM (Linear Feet per Minute) in the system is required. The SB-3642
utilizes a custom heat sink design using the conduction cooled rails to efficiently
operate within the temperature range.
MTBF (Mean Time Between Failure) report is available upon factory request.

Notes:
1. The specifications apply over the rated power supply, temperature, and reference frequency ranges.
2. Accuracy is tested in 16 bit resolution. Expect ± 1 LSB of jitter for frequencies less than or equal to 1 kHz.
3. Direct input requires SIN input, COS input, and a common ground.
4. || = “in parallel with”
5. Minimum impedance is guaranteed over the operating range, but is not tested.
6. Exceeds Tracking Rate / Bandwidth Ratio, See Table 4. An instantaneous large step angle increment can cause spin-
around condition. To avoid spin-around at power up, the default condition is 16 Bit resolution and Low Bandwidth.
7. Carrier Frequency / Bandwidth Ratio of 5X is recommended to maintain jitter < 1 LSB
8. For more information, see section on Built-In-Test (BIT) Output

3 HARDWARE INSTALLATION
The SB-3642 card is a 32-bit, 33/66 MHz PCI Local Bus Rev. 3.0 compliant interface
target device that may be inserted into any compatible slot. Note that this card is
capable of universal PCI signal and automatically defaults to 3.3V or 5V depending on
the host bus.
When installing the card, the following should be observed:
•NEVER insert or remove the card with the power turned on.
•ALWAYS take proper precautions to guard against static damage.
•Use a wrist strap if available, or ensure proper static grounding by touching the
power supply cover WITH POWER OFF.
•Insert the card at a slight angle so that the connectors first protrude from the
rear opening and then gently press the card into the motherboard connector.
Secure with proper hardware.
•Make sure that adjacent cabling and wiring do not hinder the airflow around the
card.
This card is designed as a Plug-and-Play device and as such, there are no jumpers or
switches to be set for address and interrupt selection.
3.1 Hardware Configuration and Operation
The SB-3642card utilizes the PCI interface, and the configuration for Plug-and-Play
PCI is performed by the operating system. During the initial power on boot process,
the system performs an enumeration of the PCI bus and allocates a resource
configuration that satisfies the card requirements. The system will save the
configuration information in the SB-3642’s PCI configuration space registers. These
registers are configured at the factory to contain information that identifies the card
type, vendor, required memory sizes, and interrupt resources. When the driver loads,
it will access the configuration registers and identify how the system has configured
the card. After identifying each of the installed cards, the device driver will enumerate
each of the channels on the card and create a configuration structure that defines the
allocated address and interrupt. The end user does not need to know this information
if using one of the supplied C API libraries to operate the card.

Data Device Corporation SB-3642 Manual
www.ddc-web.com Rev D – 4/19

4 DETAILED ARCHITECTURE
4.1 PCI Interface
The card provides a target 32-bit PCI interface, as defined in the PCI Local Bus
Specification, Rev 3.0, which operates at clock speeds of up to 66 MHz for
applications where a higher bus speed is desired. If a 33 MHz device was placed on a
66 MHz bus, the bus speed would be forced to slow down to 33 MHz. Although
resolver simulation may not require the additional bandwidth of a 66 MHz bus, the SB-
364266 MHz device allows the base CPU PCI bus to run at 66 MHz, enabling other
high-speed devices on the bus to take advantage of the higher bandwidth.
When using the card with the supplied Motion Feedback C SDK (SB-36030Sx) and
drivers there is no need to reference the PCI configuration registers.
Connection to the host is established through the card’s Pn1 and Pn2 connectors. PCI
64 bit extension is not supported, the PMC Pn3 for PCI 64 bit extension and Pn4 for
user I/O connectors are not populated on the card.
4.1.1 Use with 5V PCI Signaling
The PCI interface signals on the SB-3642support +3.3V or +5V signaling. The device
incorporates both 3.3V and 5V signal keying holes.
4.1.2 Register & Memory Addressing
The SB-3642PCI interface contains a set of "Type 00h" PCI configuration registers
that are used to map the device into the host system. The configuration register space
is mapped in accordance with PCI Revision 3.0 specifications. These registers are
arranged such that all memory and register space may be addressed through a single
PCI function.
Configuration registers implement the Subsystem Vendor and Device ID, and control
the Fail-Safe operation of the device. There is one Base Address Registers (BAR)
used on the design of this card. All BAR mapping is located in PCI configuration
register space.
When using this card with DDC's driver and the API library software, the details of
these registers and memory addresses are abstracted from the user to provide an
easy-to-use High Level “C” programming environment.

4.2 Synchro/Resolver to Digital Channels
4.2.1 Signal Interface
The front panel connector provides signal connections for all channels. These signals
include S1, S2, S3, S4 inputs and differential reference inputs RH and RL. See below
to identify which inputs are applicable to the selected model number.
Configuration for the resolver inputs is accomplished by the use of specific thin film
resistor networks installed on the card. These networks scale the input voltage to the
converter for a 2V, 11.8V, or 90V resolver or synchro full scale input signal.
Below are the input signal designations for synchro, resolver, and single-ended mode:
•Synchro Mode Connect (SB-36421, SB-36423, SB-36424)
- S1
- S2
- S3
- S4 is not used
•Resolver Mode Connect (SB-36422)
- S3 = +SIN
- S1 = -SIN
- S2 = +COS
- S4 = -COS
•Single-ended Mode Connect (SB-36420)
- S2 = +COS
- S3 = +SIN
When using single ended configuration, S1 and S4 need to be returned to the analog
ground using the associated analog ground pin, see pinout in Error! Reference
source not found..
4.2.1 Bandwidth
The user can program each channel independently for one of two bandwidth settings
through software. The bandwidth selection is programmable for either 80 or 300 Hz.
The bandwidth selection configures the converters’ bandwidth setting in order to
optimize signal noise rejection and dynamic response. For best dynamics, the rule of
thumb is bandwidth should be less than or equal to ¼ of the Resolver carrier
frequency, Fc.
For instance, a 400 Hz Resolver (Fc= 400Hz) should nominally have a converter
bandwidth set at 400 Hz / 4 = 100 Hz or less. In the case of SB-3642, the low
bandwidth is set to 80 Hz. This bandwidth setting would be an appropriate selection
for 400Hz carrier frequency.
