NV5500 Chapter 2 provides a description of the NV5500. It presents the following topics: • Overview • Applications • Functions • Inputs and Outputs • Operation • Summary • Configuration Overview The NV5500 is a universal sync generator. It generates NTSC, PAL, and digital audio synchroniza- tion signals locked to a common reference frequency. It generates these formats from a single time base. NTSC 75% color bars or black burst PAL 100% color bars or black burst 48 kHz AES and SDIF-2 word clock 44.1 kHz AES and SDIF-2 word clock 44.056 kHz (44.1 kHz/1.001) AES and SDIF-2 word clock The NV5500 eliminates the pops and clicks associated with sample slips owing to unlocked digital audio sample rates. It supports direct audio dubs between NTSC- and PAL-referenced VTRs and DVTRs as well as video-locked audio mixers and RDATs. The NV5500 can lock to a 5 MHz external “atomic” reference, an NTSC video input, or PAL video input. When no input is present, it uses an ultra-stable “ovenized” crystal oscillator for its master time base. A 5 MHz output is provided for locking external devices to the internal oscillator. The NV5500 is intended to function as the master time base reference for your plant. Subsequent downstream generators are intended to lock to the NV5500 as their master frequency reference and then use their own internal gen-lock to fine-tune the timing at each video or audio equipment node. S The NV5500 does not provide gen-lock. The NV5500 is designed to be installed and operated with very little effort. The input and output connections are all made with industry-standard BNC and XLR connectors. The NV5500, once installed, should operate continuously with minimal operator intervention. NV5500 Universal Sync Generator • User’s Guide 3 Functions The NV5500 generates both PAL and NTSC video simultaneously, locked to the same time base. The internal time base can be locked to an NTSC video input, a PAL video input, or a 5 MHz refer- ence. If no input reference is used, an internal oscillator provides the common time base. Generat- ing the PAL and NTSC signals locked to the same reference ensures that digital audio sample rates generated by equipment locked to video will be frequency-locked. Each video signal type has 4 independent outputs. These outputs are selectable at the front of the panel. Operators can choose color bars or black burst. PAL bars are 100% modulated; NTSC bars are 75% modulated. The internal 5 MHz signal is also provided as an output for locking additional external devices to the master time base. The stability of the internal oscillator is 0.25 ppm. The NV5500 also generates 3 AES/EBU digital audio synchronization sign
