analog nVGA links, must handle a variety of resolutions
and screen update rates. The actual range of digital
serial rates is roughly 250Mbps to 1.65Gbps. For appli-
cations requiring ultra-high resolutions (e.g., QXGA), a
“double-link” TMDS interface is used and is composed
of six data links plus the clock, requiring two MAX3815
ICs with the clock going to both ICs. See Figure 2.
The MAX3815 can be used to extend any TMDS inter-
face as used under the following trademarked names:
DVI (digital visual interface), DFP™ (digital flat-panel),
PanelLink, ADC™ (Apple display connector), and
HDMI (high-definition multimedia interface).
Loss-of-clock signal is indicated by the CLKLOS out-
put. A low level on CLKLOS indicates that the signal
power on the RXC_IN pins has dropped below a
threshold. When there is sufficient input voltage to the
channel (typically greater than 100mV
CLKLOS is high. The CLKLOS output is suitable for
indicating problems with the transmission link caused
by, for example, a broken cable, a defective driver, or a
lost connection to the equalizer.
