GeckoFlex 8943RDA-D Dual SD/HD/3G Reclocking Distribution Amplifier

The GeckoFlex 8943RDA-D unit is a dual input reclocking distribution amplifier with two electrical inputs that can be mapped to feed any of four reclocked electrical output pairs (one input per output pair). The module can distribute HD/3G-SDI or SD-SDI streams, making it ideal for mixed format applications or installations where an upgrade to HD/3G is planned. Cable equalization is up to 100 meters for HD/3G-SDI and 440 meters for SD-SDI.

All parameters can be configured directly from the card edge or via a standard HTML web browser. Module operation and configuration can be monitored using industry standard SNMP protocol via the 8900NET (Net Card) module.

Key Features

Supports SD/HD/3G-SDI rates up to 1080p
Two electrical inputs
Four electrical reclocked output pairs
Configurable input to output pair mapping
Auto or manual input format selection
100% DVB ASI compliant
High density (up to twenty DA inputs per 2 rack unit)
Remote control and monitoring via Ethernet frame interface

Application

Distributing HD/3G signals or mixed HD/3G and SD format installations
Installations where an SD to HD/3G update is planned
Installations where highest density is required at the lowest cost
For optimizing and adapting trade-off between number of DAs and number of outputs

Inputs
HD/SD-SDI: Two electrical inputs (J9 and J10)

Input equalization (Belden 1694A cable):
- 90m for 3 Gb/s (Input 1, J9)
- 100m for 3 Gb/s (Input 2, J10)
- 140m for 1.5 Gb/s
- 400m for 270 Mb/s
Return loss: >15 dB up to 1.5 Gb/s, 10 dB (typical) up to 3 Gb/s

Formats supported:

SD-SDI
HD-SDI
3G-SDI
DVB ASI

Outputs
HD/SD-SDI: Eight reclocked electrical outputs (in four output pairs: J1/J2, J3/J4, J5/J6 and J7/J8)

Return loss: >15 dB up to 1.5 Gb/s, >10 dB to 3 Gb/s
Signal level: 800 mV ±10%
Output jitter (for inputs conforming to SMPTE 259M and 292M standards):
- <0.2 UI >100 kHz for 3G
- <0.2 UI >100 kHz for HD
- <1.0 UI 10 Hz – 100 kHz for HD
- <0.2 UI 10 Hz – up for SD

DVB ASI: Eight non-inverted outputs (four output pairs)

Distribution
Reclocking: Active/bypass
Input format selection: Auto/manual
Input to output mapping: Both inputs are active at the same time and are configurable to any output pair (one input per electrical output pair).
Electrical length (input to output latency in ns):

CH1: Input J9 to Output J1:
- 3G: Reclocked: 3.8 ns, Bypassed: 3.55 ns
- HD: Reclocked: 4.0 ns, Bypassed: 3.6 ns
- SD: Reclocked: 6.0 ns, Bypassed: 4.0 ns
CH2: Input J10 to Output J1:
