External Clock input
2. CKC = High:
a. If CKC = 1, the phase lock loop (pll) is adopted in the LCd module.
b. Inputs CSY, the controller of LCD module will separate the Vertical Sync and Horizontal Synch from CSY.
c. Out put Horizontal Sync (HSY , Pin 1) and Vertical Sync (VSY , Pin 14.)
d. The internal detect will detect Vertical Sync to reset the vertical counter.
Pin 14 (VSY)
VSY output
External Vertical Sync input
3. CKC = Low:
a. If CKC = 0, the phase lock loop (PLL) is not adopted in the LCD module.
b. If CKC = 0, the external clock input frequency of Pin 3 is 6.4 MHz.
c.
Input external Vertical Sync. (VIY , Pin 17) and Horizontal Sync. (Pin1) to synchronize the LCD module. External Horizontal Sync and External Vertical
Sync. input pulse can be high going or low going.
d. The pulse width of external Horizontal SYnc. input is 4.7 µs ±2 µs. The pulse width of external Vertical Sync. input is 2H~4H.
e. The pulse length of external input Vertical Sync. of system is 262H ±4H.
4. If there is any question about CKC = 0, please contact Purdy Electronics.
5. V_GH TYP._+17V ; V_GL TYP._-15V ; V_DD TYP._+5V ; V_CC TYP._+5V
6. The frequency of PSI is 15.75 KHz.
7. Pin 16 (COMPS) can select composite sync. mode OR sync. separate mode
