TH7834C
Readout Shift Register
Clocking
All gates of the 4 CCD shift registers are separated, enabling two or four output readout
modes.
To select 2 or 4 outputs operating mode, register main transport gates must be con-
nected as described here after:
• 4 outputs mode:
V_OS1: Φ_L1 = Φ_2A + Φ_3A; Φ_L2 = Φ_1A + Φ_4A
V_OS2: Φ_L1 = Φ_2B + Φ_3B; Φ_L2 = Φ_1B + Φ_4B
V_OS3: Φ_L1 = Φ_2C + Φ_3C; Φ_L2 = Φ_1C + Φ_4C
V_OS4: Φ_L1 = Φ_2D + Φ_3D; Φ_L2 = Φ_1D + Φ_4D
• 2 output mode: V_OS1 and V_OS2:
V_OS1: Φ_L1 = Φ_2A + Φ_3A + Φ_1C + Φ_2C
Φ_L2 = Φ_1A + Φ_4A + Φ_3C + Φ_4C
V_OS2: Φ_L1 = Φ_2B + Φ_3B + Φ_1D + Φ_2D
Φ_L2 = Φ_1B + Φ_4B + Φ_3D + Φ_4D
• 2 output mode: V_OS3 and V_OS4:
V_OS3: Φ_L1 = Φ_1A + Φ_2A + Φ_2C + Φ_3C
Φ_L2 = Φ_3A + Φ_4A + Φ_1C + Φ_4C
V_OS4: Φ_L1 = Φ_1B + Φ_2B + Φ_2D + Φ_3D
Φ_L2 = Φ_3B + Φ4B + Φ_1D + Φ_4D
Note: In 2 output mode, the unused outputs can be connected as following:
• Φ_LS = Φ_R = V_GS = 0V
• 10V < V_DR < 15V
• V_DD = 15V
• V_S not connected in order to cancel unused output amplifiers power consumption.
