General Description
The PCI-CTR20HD from Measurement Computing is a 20 channel, up or down counter/timer board for PCI-bus and PCI-X computers. The board offers a unique blend of high density, high performance and low cost. User connections to the input, output and gate of each counter are provided through a single high density 100 pin connector.
The board is based on 4 CTS9513 counter/timer chips. Each 9513 provides five 16-bit counters. The 9513 is extremely powerful and flexible and is software programmable for event counting, pulse width and frequency measurement and generation. The 9513 can also generate complex duty cycle outputs in continuous and one-shot modes. Counters on the 9513 can be cascaded via software control, enabling 32, 48, 64 and 80-bit counters without requiring any hardware connections.
The maximum allowable input frequency is 6.8 MHz, with a minimum pulse width of 70 nS. Software allows each counter to be connected to on-board 1, 1.67, 3.33 and 5 MHz on-board clocks (1.67 and 3.33 MHz based on 33 MHz PCI clock) sources for time-base generation. The board also provides two user interrupt inputs.
