Descriptions

Address Code Definition:
10-bit parallel binary code A0–A9, compatible with CMOS and TTL logic levels.

· A0–A7 control voltage levels: Logic Low: 0 ~ 0.7 V; Logic High: 2.4 ~ 3.3 V.

· A0–A7 are used as the in-band address code.

· A8 and A9 are used as band selection codes.

Address Calculation (rounded to integer)

Address Code={(fx-flow）/(fhigh-flow)}*250 

Where:

·  fx: desired intra-segment center frequency

·  flow: lowest frequency in the segment

·  fhigh: highest frequency in the segment

·  250: intra-segment steps

If the calculated result contains a decimal fraction, it shall be rounded to the nearest integer.
