*1. A, AN, B, BN, Z, and ZN terminals.

*2. DA, DB, DZ, IO1, IO2, and IO3 terminals.

*3. The angular error expresses the variation from the ideal phase difference of interpolation outputs DA and DB as a phase difference of the input period.

Converting 3° and expressing as a percentage of the output period gives 13.3% using equation (1) below.

(where 16x is the interpolation factor)
