gm2115/25 Preliminary Data Sheet
June 2002

C2115-DAT-01B
4.11.2 Programmable Row Driver Interface
The gm2115/25 row driver interface supports 2 and 3 voltage row drivers.
The row driver interface consists of the following signals. The starting time and pulse-width
of each are fully programmable.
RSP2
– Row Starting Pulse for 2 voltage Row Driver
RSP3
– Row Starting Pulse for 3 voltage Row Driver
RCLK
– Row/Vertical shift clock
ROE
– Row Output Enable or Row Blank Time or Gate Driver Output Enable. This signal
is used to control RC discharge time. Note that some vendors support three ROE’s for this
function to avoid 2 lines being activated at the same time (ROE2 and ROE3 are optionally
available on pins GPIO9 and GPIO10). The polarities of ROE, ROE2 and ROE3 are
programmable. These signals can be blanked during horizontal and/or vertical blanking to
reduce power. In addition, ROE, ROE2 and ROE3 may be staggered.
RCLK, ROE, ROE2 and ROE3 have programmable polarities and can be blanked during
horizontal and/or vertical blanking period (programmable) to reduce power. Note that ROE2
and ROE3 can be used to drive GV and GVOFF signals required by some row driver ICs.
See the gm5115/25 Programming Guide (C5115-DSR-01) for details regarding row driver
programming.
4.11.3 Reduced EMI
The gm2115/25 programmable TCON has many features that can be used to reduce
electromagnetic interference (EMI). These include transition minimization, data staggering,
data swapping for reduced trace length (even with odd, red with blue and bit 0 with bit 7),
slew rate control and dual-edge clocking.
In addition, the DP_CLK generation circuit features a proprietary method for the reduction of
electromagnetic interference (EMI) emitted by the display port. High spikes in the EMI
power spectrum may cause LCD monitor products to violate emissions standards.
