CM2009
Product Description (cont’d)
Two non-inverting drivers provide buffering for the
HSYNC and VSYNC signals from the video controller
IC (SYNC1, SYNC2). These buffers accept TTL input
levels and convert them to CMOS output levels that
swing between Ground and V
CC_SYNC
, which is typi-
cally 5V. Additionally, each driver has a series termina-
tion resistor (R
T
) connected to the SYNC_OUT pin,
eliminating the external termination resistors typically
required for the HSYNC and VSYNC lines of the video
cable. There are three versions with different values of
R
T
to allow termination at typically 65
(CM2009-00)
or 55
(CM2009-01) or 15
(CM2009-02).
The 15
(CM2009-02) version will typically require two
external resistors which can be chosen to exactly
match the characteristic impedance of the SYNC lines
of the video cable.
Two N-channel MOSFETs provide the level shifting
function required when the DDC controller is operated
at a lower supply voltage than the monitor. The gate
terminals for these MOSFETS (V
CC_DDC
) should be
connected to the supply rail (typically 3.3V) that sup-
plies power to the transceivers of the DDC controller.
