3 Description
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 chargesharing,
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.
