Zero cross timer setting
If the input signal is lower than the zero cross comparator detection sensitivity, or if a low-frequency signal is input, the
state in which the circuit cannot detect a zero cross may continue and the input data will not be latched during that
period.
The zero cross timer sets a time for the data to be latched forcibly in states such as this where a zero cross cannot be
detected.
For example, to set a 25 ms time:
T = 0.69 CR
Assume C = 0.068 F. The R will be:
25
× 10–3
R = —————————
≈ 530 k
0.69
× 0.068 × 10–6
Normally, a time in the range 10 to 50 ms is used.
Notes on serial data transfer
(1) Cover the CL, DI, and CE signal lines with the ground pattern or use shielded lines to prevent the high-frequency
digital signals carried by these lines from entering the analog signal system.
(2) The LC75348 and LC75348M data format consists of 8 bits of address and 32 bits of data. When transmitting data
as an even multiple of 8 bits (when transferring 36 bits of data), use the data format shown below.
