HT6026

Functional Description

Operation

The HT6026 encoder begins a one-word transmission cycle upon receipt of a transmission enable (TE,

active low). This cycle will repeat itself as long as the transmission enable (TE ) is held low. Once the

transmission enable returns high, the encoder output completes its final N×2 word cycle, and then

stops as shown in Figure 1. The total number of transmission cycles allowed is always adjusted to an

even number automatically.
