Analog Genlock
Analog Generator (A10
Main Board Only)
The analog genlock consists of the following blocks:
Genlock Controller. This block controls the A/D converter, memory, and sync separator to obtain correct digital data.
A/D Converter. The A/D converter digitizes the analog input signal to 10-bits digital data for genlock operation. This data is read by the CPU and used to control the master oscillator frequency.
Sync Separator. The sync separator separates the sync signal such as H sync or V sync from the input signal.
Amp & Restorer. This block consists of amplifiers to adjust the amplitude of the signal from the REF input and restorer to recover the DC component of the signal.
The analog generator consists of the following blocks:
Sync Memory. The sync memory is a part of the FPGA and keeps the data of the sync pulses.
Line Memory. The line memory is a part of the FPGA and contains the active part of the line data of the test signal. It can store up to four line data.
SDI Generator
Frame Memory. The frame memory contains a series of pointers that control the
order of the video lines stored in the Line Memory, which are used to produce digital signals.
Overlay Memory. The overlay memory ge nerates timings to multiplex the line memory data and the overlay data used for an ID text and logo overlay.
Delay Counter. The delay counter in the FPGA sets the timing of each channel. The optional fine timing feature is achieved by digital filter technique.
Signal Generator. This block builds complete test signal sequence with sync and line data according to the frame memory.
D/A Converter and Amplifier. This block consists of a D/A converter, an amplifier, and a filter. It converts the digital data from the Signal Generator to an analog signal and reconstructs the signal for output.

Adjustment

Adjustment Procedure

This section contains information needed to adjust the sync pulse generator.
The only adjustment in the sync pulse generator is for the master clock frequency.

Requirement for Adjustment

Before proceeding, note the following requirement:
Warm-up Period
The sync pulse generator requires a 20 minute warm-up time in a +20 °C to +30 °C environment before it is adjusted. Adjustment done before the operating temperature has stabilized may cause errors in performance.
In addition, the signal generator requires appropriate warm-up time to meet the frequency accuracy.
