Eindhoven, The Netherlands — JTAG Technologies has introduced MAC-Panel Scout Mass Interconnect System — a new JTAG/boundary- scan hardware interface product compatible with the MAC-Panel Scout mass interconnect system. The JT 2147/DAK is a signal conditioning module that allows seamless connec- tions from JTAG Technologies’ PXI DataBlaster to the Scout’s connec- tion system.
wiring tasks and, at the same time, retain the excellent signal integrity assured by the QuadPod’s active interface. The JT2147/DAK has four inde-
pendent JTAG Test Access Ports (TAPs) along with 16 user assigned Digital I/O channels. Each TAP can be programmed to operate through a range of voltage levels to suit various logic families. Another new entry is AutoBuzz,
the most exciting addition yet to their no-netlist-required range of JTAG/boundary-scan test and debug tools. AutoBuzz is an amazing tool that uses a special “seek and discov- er” feature to scan completely a com-
pliant design and then perform com- parative tests using JTAG/boundary- scan.
With only JTAG scan-chain
information plus BSDL models of the JTAG/IEEE std 1149.1 compliant parts (available from manufacturers’ web-sites), users of AutoBuzz will be able to connect to their designs using a number of compatible JTAG inter- face options. AutoBuzz can then be set to gather a complete “connectivi- ty map” of any board’s boundary- scan to boundary-scan pin connec- tions — where these can be direct or via “transparent” devices such as series resistors. AutoBuzz supports just two
simple operating modes: Learn and Compare. With AutoBuzz in Learn mode a “known good” sample PCB is initially scanned to establish a refer- ence connectivity map. Suspected faulty boards can then be scanned by AutoBuzz in Compare mode, and a comparison is automatically made of their connectivity maps. Differences between the two maps are highlight- ed to indicate possible faults such as interconnect short-circuits, open-cir- cuits or “stuck-at” faults. Contact: JTAG Technologies,

New hardware and software for boundary scan.
Based on the highly successful
QuadPod architecture from JTAG Technologies, the JT 2147/DAK has been specifically designed in the MAC Panel “Direct Access Kit” (DAK) form factor. In using the JT 2147/DAK, test system builders will be able to greatly simplify their
Wideband VCO from Crystek
Fort Myers, FL — Crystek’s CVCO - 55CW -1200-2100 VCO (Voltage Controlled Oscillator) operates from 1200MHz to 2100MHz with a control voltage range of 0.5V to 25V. This VCO has a typical phase noise of - 95dBc/Hz at 10kHz offset and report- edly has excellent linearity. Output power is typically +6dBm.
Wideband VCO. Engineered and manufactured
in the USA, the new VCO is pack- aged in the industry-standard 0.5 x 0.5-in. (12.7 x 12.7mm) SMD pack- age. Input voltage is 12V, with a max. current consumption of 35mA. Pulling and Pushing are minimized to 25.0MHz and 10.0MHz/V, respec- tively. Second harmonic suppression is -8dBc typical. The CVCO55CW-1200-2100 is
suitable for use in applications such as digital radio equipment, fixed wireless access, satellite communica- tions systems, and base stations. Contact: Crystek Corporation,
