What is the difference between an adapter and a pin converter?
A pin converter is a part where signals are directly routed between two
different connectors. There is no signal buffering or logic between the pins. An
adapter is a part that has added logic, such as buffering signals or providing
a special function (i.e. ARM adaptive clocking). The adapter may also have two different
connectors, acting as a pin converter in addition to its logic. Both a pin converter
and an adapter usually consist of a small PCB with emulator and target board connectors
and are designed to be installed between the emulator’s JTAG cable connector
and the target board’s emulator connector.
Which type do I need?
Please contact Blackhawk or your local Blackhawk Reseller for information on what
pin converter or adapter is necessary for our emulators and these new targets. In
most cases, you may not need an adapter. For example,
all Blackhawk XDS510 and XDS560-class JTAG emulators, currently shipping in production,
do not need a low voltage adapter. Blackhawk emulators support automatic
target voltage detect by sensing the voltage provided by the target board on pin
5 of JTAG header from 0.5 5.0 volts. Pin 5 was originally referred to the
PD pin (presence detect), but you may see the new TVD abbreviation (target voltage
detect).
Naming Abbreviations
The following describes the naming of an adapter or pin converter, which reads from
left to right, or, for the actual adapter PCB, it is interpreted top to bottom.
##e_typeE-##t_typeT
- ## Is the number of pins (14, 20, 60, etc.)
- e emulator connection
- t target connection
- typeE Describes the emulator connection type (TI, cTI, ARM, etc)
-
typeT Describes the target connection type (TI, cTI, ARM, etc.)
The hyphen (-) separate the two types of connections (emulator and target). The
absence of a notation as _typeE or _typeT in either emulator or target connection
type, assumes that the emulator or target is a TI device or compatible (i.e. “_TI”).
Examples
These are some examples of adapter and pin converter names.
- 14e-20t_cTI Pin Converter
This naming describes a pin converter with the emulator connection being a standard
14-pin TI header (the type “_TI” omitted from left side of hyphen) that
has a target end socket with the cTI 20-pin configuration for connection to a target
board with a cTI 20pin header (i.e. Davinci EVM).
How do I know what pin converter or adapter I need for the DV-EVM?
- 14e_TI-20t_ARM Adaptive Clocking Adapter
This naming describes an adapter that contains additional logic to support adaptive
clocking with the emulator connection being a standard 14-pin TI header that has
a target end socket with the 20-pin ARM configuration for connection to a target
board with a 20pin ARM header (i.e. OSK with Multi ICE header).
- 20e_cTI-20t_ARM Pin Converter
This naming describes a pin converter with the emulator connection being the new
compact TI (cTI) 20-pin header pins routed to a target end socket with the 20-pin
ARM configuration.
- 14e_TI-60t_TI Pin Converter
This naming describes a pin converter with the emulator connection being a standard
14-pin TI header that has a target end socket with the TI 60-pin configuration for
connection to a target board with a 60-pin header (i.e. C6416 DSK).
- 14e_TI-14t_TI Low-voltage Adapter
This naming describes an adapter with the emulator connection being a standard 14-pin
TI header that has a target end socket with the same standard 14-pin TI header with
added logic to support low-voltage targets.
