... GS9076 can be configured to either automatically or manually enter a bypass mode in order to pass the signal without reclocking. The GS9076 offers a choice of dual reclocked data outputs or one data output and one recovered clock output. The device is footprint and drop-in compatible with existing GS2975A designs, with no additional application changes required ...

... The GS9076 is a SD-SDI Serial Digital Reclocker designed to automatically recover the embedded clock from a digital video signal and re-time the incoming video data. The GS9076 will recover the embedded clock signal and re-time the data from a SMPTE 259M-C compliant digital video signal. Using the functional block diagram ...

... Second is the phase acquisition (PA) loop. Once locked, the PA loop tracks the incoming data and makes phased corrections to produce a re-clocked output. The internal VCO of the GS9076 oscillator trimmed at the time of manufacture to capture all data rates over temperature and operation voltage ranges. ...

... Figure 4-2: Phase Detector Characteristics When the PA loop is active, the crystal frequency and the incoming data rate are compared. If the resultant is more that 2%, the PLL is considered to be unlocked and the system jumps to the FA loop. 44617 - 1 January 2008 GS9076 Data Sheet 0.8UI ...

... This helps to eliminate crosstalk from potential noise that would couple to the unused input pair. The GS9076 can be configured to manually lock to a specific data rate or automatically search for and lock to the incoming data rate. The AUTO/MAN pin selects automatic data rate detection mode (Auto mode) when HIGH and manual data rate selection mode (Manual mode) when LOW ...

... Bypass Mode 4.9 Lock and LOS In Bypass mode, the GS9076 passes the data at the inputs directly to the outputs. There are two pins that control the bypass function: BYPASS and AUTOBYPASS. When BYPASS is set HIGH, the GS9076 will be in Bypass mode. When AUTOBYPASS is set HIGH, the GS9076 will be configured to enter Bypass mode only when the PLL has not locked to a data rate ...
