4.0 Application Information
4.1 Clock Interfacing
Because of the high clock rates at which the Bt457 and Bt458 can operate, they
will accept differential clock signals (CLOCK and CLOCK*). These clock inputs
are generated by ECL logic operating at +5 V The CLOCK and CLOCK* inputs
require termination resistors (220
to GND) that should be located as close as
possible to the clock driver. A 150
chip resistor connected between the
RAMDAC
’
s CLOCK and CLOCK* pins is also required to ensure proper
termination. It should be located as close as possible to the RAMDAC.
Figure 4-1
illustrates the location.
