Convolutional Encoder

KEY FEATURES

Note: The newer COM-1509 now provides higher performance (120 Mbps) and extended functionality (full codec, scrambling, HDLC, etc.)

Convolutional encoder for error correction

Selectable rate and constraint length:

• K = 5, rate 1/7
• K = 7, rates ½, 2/3, ¾, 5/6, 7/8
• K = 9, rates 1/3, ½, 2/3

Treillis Coding Modulation (TCM) encoder:

• Rate 2/3 (8-PSK)
• Rate ¾ (16-PSK)

Continuous or Block mode operation

Support for the following standards:

• Intelsat IESS-308/309
• Intelsat IESS-310
• DVB ETS 300 421
• DVB ETS 300 744

Differential encoder

Maximum throughput (at output): 40 Mbps

On-board or external clock selection

ComScope–enabled: key internal signals can be captured in real-time and displayed on a host computer

Single 5V supply

Connectorized 3”x 3” module for ease of prototyping. Standard 40 pin 2mm dual row connectors (left, right). Interfaces with 5V and 3.3V logic
