Genlock Function
Loop-Through Input |
| Input Configuration |
BNC connector, 75Ω loop-through |
| Return Loss |
≥30 dB (0.3 MHz to 30 MHz) |
| Reference Input Signal |
HDTV tri-level sync signal conforming to SMPTE 240M/274M/296M standards
525p/625p analog sync signal conforming to SMPTE 293M/ITU-R BT 1358 standards
NTSC black burst signal conforming to EBU N14/SMPTE RP-154/SMPTE 170M/SMPTE 318M standards
PAL black burst signal conforming to ITU-R BT. 470-6 standards |
| Reference Input Signal Level |
HDTV: Positive polarity: 300 mV
Negative polarity: -300 mV
525p/625p: -300 mV
NTSC: -286 mV
PAL: -300 mV |
| Maximum Input Level |
±4.5 V |
| Operating Input Level Range |
±6 dB |
| External Lock Range |
±10 ppm |
| Jitter |
≤0.5° in burst lock mode
≤1 ns in sync lock mode |
| Operation Modes |
AUTO and MANUAL modes are provided for selecting INT or EXT mode.
AUTO Mode: The EXT is automatically selected when the reference signal is applied to the GENLOCK input; removing the reference signal automatically selects the INT.
MANUAL Mode: The operation mode is selected by using the menu. (The INT is always selected when no reference signal is applied, or the signal format differs from the format selected in MANUAL mode.) |
| Genlock Timing Variable Range |
H-PHASE
(FINE): Fine adjustment between the H-PHASE (COARSE) steps.
H-PHASE
(COARSE): ±1/2 line with respect to the input signal
Resolution: 0.0741μs
V-PHASE: ±1 field with respect to the input signal
(±1/2 frame with respect to the input signal in progressive mode)
Resolution: 1 line
F-PHASE: Up to ±5 frames with respect to the input signal.
(Variable range depends on the input signal format.)
Resolution: 1 frame
(When NTSC black burst is applied, the coincident point of line 4 of the PAL and line 1 of the HDTV is handled as a reference. When PAL black burst is applied, the coincident point of line 1 of the PAL and line 1 of the HDTV is handled as a reference.) |
