announced the release of the user-configurable Model 7191 programmable clock
synthesizer PMC module. Like its predecessor, the Model 7190, the new Model
7191 gives designers working with A/Ds and D/As a highly precise clock source with
the added flexibility of custom frequency generation under simple software
Model 7191 achieves its combination of flexibility and performance by using
low-noise VCXOs for the fundamental frequency generation. The VCXO output is
followed by a clock synchronizer from Texas Instruments to allow synchronization
with common frequency reference sources.
The Model 7191 generates four different user-programmable
VCXO frequencies, plus four divided versions (by 2, 4, 8 and 16) of each
oscillator. Using the provided software, users can freely route up to five
different frequencies from this set of 20 choices to the board's eight buffered
It also helps streamline development by being easy to
integrate into popular system architectures. The board's base format is an
industry-standard PMC module with 32-bit
33/66 MHz PCI interface, usable on any type of carrier that supports PMC. Pentek also offers this module on simple
carriers for PCI, PCIExpress, CompactPCI, VME and VPX form factors.
For Linux, Windows, or VxWorks operating systems, the 7191
is supported with the ReadyFlow Board Support Package with full control over and
status of board operation across the PCI bus. The board is also equipped with
non-volatile configuration memory for dedicated operation in systems without
The price of the Model 7191
Multifrequency Programmable Clock Synthesizer is $2,995 USD and delivery is from
inventory to four weeks ARO.
