APPLICATION INFORMATION
clock interfacing
To facilitate the generation of high-frequency clock signals, CLK and CLK are designed to accept differential
signals that can be generated with 5-V (single-supply) ECL logic. Due to noise margins of the CMOS process,
CLK and CLK must be differential signals. Connecting a single-ended clock signal to CLK and connecting CLK
to GND does not work. CLK and CLK require termination resistors (220
to V
DD
and 330
to GND) that should
be as close to the device as possible.
LD is typically generated by dividing the clock frequency by four (4:1 multiplexing) or five (5:1 multiplexing) and
translating the resulting signal to TTL levels. Since no phase relationship between the LD and CLK signals is
required, any propagation delay in LD caused by the divider circuitry does not affect device performance.
The pixel, overlay, sync, and blank data are latched on the rising edge of LD. LD may also be used as the shift
clock for the video DRAMs. In short, LD provides the fundamental timing for the video system.
The Bt438 clock generator (from Brooktree) is recommended for generating the CLK, CLK, LD, and REF
signals. It supports both 4:1 and 5:1 multiplexing. Alternately, the Bt438 can interface the device to a TTL clock.
Figure 5 illustrates the interconnection between the Bt438 and the device.
