Hi Sir,
Pls kindly help for below questions for DIR9001, thanks.
- What different between PLL "lock" and "unlock"? How to switch between?
- AUDIO and EMPH are channel status, what function for these two pins?
- COUT, UOUT are LR clock of biphase input ?When will use these two pins?
- CLKST is necessary? Looks it will change follow PLL lock/unlock (active H), but "ERROR pin" can know PLL clock, is it?
- Most of DIR9001 pinout are o/p, what pins will need connect to SOC (ERROR, BFRAME, EMPH, COUT, UOUT, AUDIO, CLKST..)?
Thanks, Ian.
