Two 32-bit comparators

One 32-bit preload register

Clock frequency 40MHz

Counter Modes

Single count

1x quadrature, 2x quadrature, 4x quadrature

Frequency measurement

Pulse width "high", pulse width "low"

Input

3 inputs for each counter

RS422, TTL or 24V input

Timing characteristics for the different modes:
• Single count: t high > 200ns; t low > 200ns
• Quadrature: time between two active edges (t edges > 400ns)
• Frequency measurement: gating time 10ms, < 2.5MHz
• Pulse width: t high or t low > 15µs
• Period: t high or t low > 15µs, internal frequency 2.5MHz
• Synchronization of input signals with onboard clock (40MHz)

Input debouncing time: 100ns

RS422 input characteristics: see user manual

TTL input characteristics:
• Uin < 0.5V = "low"
