11 / 56 page THCV231_THCV236_Rev.2.30_E Copyright©2016 THine Electronics, Inc. THine Electronics, Inc. 11/56 Security E Spread Spectrum Clock Generator (SSCG) The THCV231 serial data output and the THCV236 parallel data and clock outputs are modulated by programmable SSCG. The THCV231 and THCV236 SSCG are enabled by only SSEN register. The modulation rate and modulation frequency variation of output spread is controlled through the SSCG control registers on each device. Do not enable spread spectrum for both the THCV231 and THCV236 at the same time. Table 6. SSCG enable signal Mode Entry Signal Description SSEN(register) 0:SSCG Disable 1:SSCG Enable When customer use the mode and frequency range shown in Table 7, register setting is required according to Table 8.
