The INNOSILICON DLL PHY provides the low power and high-speed applications with robust timing and small silicon area. According to the reference clock, an accurate 0/90/180/270 phase clock with the same frequency as the reference clock can be generated. The DLL PHY components contain DLL specialized functional and utility DLL up to 800Mbps in SMIC 28nm, critical timing synchronization module (TSM) and a low power/jitter DLLs with programmable fine-grain control for any DLL application.
