HD3-6409C-9

Encoders, Decoders, Converters Overview

The HD3-6409C-9 is a high-speed, low-power CMOS Manchester Encoder-Decoder manufactured using self-aligned silicon gate technology. It operates in two distinct modes: converter mode for NRZ-to-Manchester encoding and decoding, and repeater mode for reconstructing Manchester code with a recovered clock via a digital phase lock loop. The device supports data rates up to 1 Mbps while consuming only 50 mW typical power at +5V. Key electrical characteristics include static operation capability, on-chip oscillator functionality, and low bit error rate performance. It is designed for serial data communication applications requiring noise immunity and DC component elimination.

Encoders, Decoders, Converters Procurement Notes

Verify the specific suffix 'C-9' against official Harris Corporation documentation to confirm temperature range and package variations. Ensure compatibility with existing system voltage levels and clock requirements before procurement. Cross-reference part numbers with current manufacturer databases as legacy components may have superseded versions or obsolescence notices.

Encoders, Decoders, Converters Selection Notes

Select this component when Manchester coding is required for serial data transmission to ensure clock recovery and noise immunity. Consider the 1 Mbps maximum data rate and 50 mW power consumption constraints. Verify interface compatibility with downstream protocol controllers and ensure the SOICW package fits the target PCB layout. Evaluate if the digital PLL clock recovery meets the jitter specifications of the application.

Encoders, Decoders, Converters Part Context

The HD3-6409C-9 belongs to the HD-6409 family of Manchester Encoder-Decoders. This series is designed for high-speed serial communication where data accuracy is critical. The device provides a solution for converting between NRZ and Manchester codes, addressing deficiencies inherent in NRZ signaling such as DC bias and lack of embedded clock information.

Encoders, Decoders, Converters Replacement Considerations

Check for direct pin-compatible substitutes within the HD-6409 family. Verify functional equivalence regarding data rate limits and power consumption. Confirm that any replacement maintains the same Manchester encoding/decoding logic and PLL characteristics.
