IMAGENICS / CRO-HDC1A

A low-cost, space-saving 3G/HD/SD-SDI D/A converter with analog audio selectable output and video down-conversion function. [LF] Embedded audio can be selected from a total of 8 channels (Group 1 and 2) for D/A conversion, making it ideal for surveillance monitoring applications and featuring audio meter display.

■3G/HD/SD-SDI Down & D/A Converter
[Input Signal Section]
■3G/HD/SD-SDI Input Signal:

NRZI 0.8 V(p-p) 75 Ω 1 line (BNC x 1)
3G-SDI SMPTE424M/425M-AB
HD-SDI SMPTE292M
SD-SDI SMPTE259M-C Compliant
■Input Cable Compensation Capability
3G-SDI 100 m (5CFB coaxial)
HD-SDI 150 m (5CFB coaxial)
SD-SDI 200 m (5C2V coaxial) (For each pathological signal)
■ Active Through Output
NRZI 0.8V(p-p) 75Ω x 1 (BNC x 1)
SDI input signal is cable equalized and reclocked before being distributed to the output
■ Signal Format:
3G-SDI 1080p@59.94
HD-SDI 1080i@59.94
SD-SDI 480i@59.94 (10-bit each)

[Video Output Signal]
■ Analog Video Output:
Select either one YPbPr color-difference signal or one VIDEO signal, distributed to three channels, each 75Ω (BNC x 3)
When YPbPr color-difference signal is selected: Y: 1.0 V(p-p), PbPr: 0.7 V(p-p)
When VIDEO signal is selected: 1.0 V(p-p) Compliant with SMPTE 170M Standard
■Video Frequency Response
HD Output: Y: 30 Hz to 20 MHz, -1 dB to +1 dB, to 30 MHz, -2 dB
PbPr: 30 Hz to 10 MHz, -1 dB to +1 dB, to 15 MHz, -5 dB
SD Output: Y: 30 Hz to 6 MHz, -1 dB to +0 dB
PbPr: 30 Hz to 2.5 MHz, -3 dB to +1 dB
(Except when down-converted output is in operation)
■Video Quantization:
YPbPr or VIDEO signal, 12 bits each (digital x4 to x16 oversampling processing supported)
■Field of View Settings for Down-Conversion Choose from 16:9 squeeze, 4:3 side cut, 14:9 letterbox, or 16:9 letterbox.
■ Video absolute delay:
D/A conversion output for 3G-SDI input/HD output: 1 ms (or less).
D/A conversion output for HD-SDI input/HD output: 2 us (or less).
D/A conversion output for SD-SDI input/SD output: 5 us (or less).
Down-conversion output for 3G/HD-SDI input: 3 ms (or less).

[Audio Output Signal]
■ Audio Standard:

Embedded digital audio compliant with SMPTE 299M and SMPTE 272M-C standards.
■ Analog audio output
-10dBu (10kΩ load or more) unbalanced 2-channel stereo (RCA x 2)
Maximum output level: +10dBu (when embedded audio is 0dBFs) * Analog audio output is possible by selecting or mixing odd-numbered channels from Group 1 and even-numbered channels from Group 2 to output 1ch and 2ch, respectively.
■Audio quantization, signal-to-noise ratio:
48kHz 24bit 80dB (or more)
■Audio frequency response:
20Hz to 20kHz -1dB to +1dB (or less)
■Audio distortion:
0.03% (or less) (-10dBu output 1kHz)
■Absolute audio delay: 2ms (or less)
■Other features:
Input SDI signal display, color bar and test pattern output, etc.
