Timing Parameters and Ext Triggering

The timing tables accompanying each of the triggering diagrams that follow indicate the exposure and cycle times achievable in each triggering mode for the Zyla. These are based on Frame and Row Periods as shown below.

Timing Parameters and Ext Triggering for Zyla 5.5

Timing Parameters based on Sensor Clock Speed (Zyla 5.5)

Parameter	Sensor Readout Rate
Parameter	200 MHz	560 MHz
1 Row (2624 clock cycles)	25.41 µs	9.24 µs
1 Full Frame (2160 rows)	27.44 ms	9.98 ms

The time taken to read out a full row is equal to 2624 clock cycles. The sensor is split into 2 halves with each having an independent data output from the sensor. This means the Frame Period is 1080 rows x 2624 clock cycles. For sub-images the frame readout time is related to the number of rows being displayed.

In External and External Start Triggering Modes, the minimum trigger pulse width detected by the Zyla 5.5 camera is shown below in Minimum EXT Trigger Width (Zyla 5.5)

Minimum EXT Trigger Width (Zyla 5.5)

Parameter	Sensor Readout Rate
Parameter	200 MHz	560 MHz
EXT Trig Pulse Width ( 2 clock cycles)	19.37 ns	7.04 ns

Timing Parameters and Ext Triggering for Zyla 4.2

The timing tables accompanying each of the triggering diagrams that follow indicate the exposure and cycle times achievable in each triggering mode for the Zyla 4.2. These are based on Frame and Row Periods as shown below.

Timing Parameters based on Sensor Clock Speed (Zyla 4.2)

Parameter	Sensor Readout Rate
Parameter	216 MHz	540 MHz
1 Row (2592 clock cycles)	24.00 µs	9.60 µs
1 Full Frame ( 2048 rows)	24.54 ms	9.83 ms

The time taken to read out a full row is equal to 2592 clock cycles. The sensor is split into 2 halves with each having an independent data output from the sensor. This means the Frame Period is 1024 rows x 2592 clock cycles. For sub-images the frame readout time is related to the number of rows being displayed.

In External and External Start Triggering Modes, the minimum trigger pulse width detected by the Zyla 4.2 camera is shown below in Minimum EXT Trigger Width (Zyla 4.2)

Minimum EXT Trigger Width (Zyla 4.2)

Parameter	Sensor Readout Rate
Parameter	216 MHz	540 MHz
EXT Trig Pulse Width ( 2 clock cycles)	20 ns	7.4 ns
