Programmable Fire Pulse

The fire-pulse generator generates a sequence of pulses which is highly programmable in frequency, phase and number of pulses. The high-speed oscillator frequency is used as the basic frequency. This frequency is internally doubled and can freely be divided by a factor of 2 to 15. It is possible to generate 1 to 15 pulses . For each pulse the phase can be adjusted per register configuration.

The fire-pulse generator provides 2 outputs. The driver strength of each output is 48 mA @ 5V . These 2 outputs can be paralleled to increase the driver strength up to 96 mA . Furthermore each output signal can be inverted to double the signal amplitude. The outputs can be set individually high-Z.

The fire-pulse generator allows to generate and send pulse sequences multiple times for use in a quasi sing-around method. Using this feature the received pulse sequence is fed into TDC-GP2 Fire_In input. It is digitally amplified and directly forwarded to the output buffer for an immediate re-emittance without any clock delay.
