Video Mode Timing—SGD Video Mode
Item Description Min. Max. Units
1 HS high time 30 nsec
2 Last VCLK fall to HS fall 20 nsec
3 HS to VCLK rising edge 10 nsec
4 R/G data setup to VCLK 10 nsec
5 R/G data hold from VCLK 10 nsec
6 VCLK period 100 nsec
7 VCLK low width 30 nsec
8 VCLK high width 30 nsec
9 VS high setup to HS low 140 nsec
10 VS hold after HS 140 nsec
11 VS low setup to HS high 140 nsec
12 HS period 34 usec
VS period 240 HS periods
VS frequency 120 Hz
Notes: 1) The first HS falling edge occurring when VS is high indicates the first row
2) The video data for a given row is clocked in prior to the falling edge of HS
3) The first 320 VCLK falling edges after the fall of HS clock in the valid data
4) If video inputs are halted, the previously clocked in data will be displayed
5) Video frame dithering/gray scale may cause artifacts due to the frame buffer
6) All timing measurements are made at 1.6V
