PRODUCTION DATA.
The TPS65197/B is an 8-channel level-shifter with discharge function intended for use in LCD display applications such as Notebooks, Monitors and TVs.
The device converts the timing-controller (T-CON) logic-level signals to the high-level signals needed by the gate-in-panel (GIP) display.
The clock outputs, CLKOUTx, support normal level shifting operation and 2-channel or 3-channel charge-sharing, which can be used to improve picture quality and power consumption. At power down, all outputs follow their input signals as long as possible; when the discharge function is used, the outputs are pulled high (VGH).
The TPS65197 implements a logic reset to ignore wrong T-CON signals after the rising STV edge which forces all 6 output clocks to VGL1. The next CLKIN1 rising edge unlocks the logic and enables normal operation. The TPS65197B does not have the logic reset and always follows its input signals.
