13.1.1
The timing of address, data and control are all related to the system clock which is also used by the external
SSRAM to clock these signals. Therefore the propagation delay of the clock to the ZL50110/11/14 and the SSRAM
must be matched to within 250 ps, worst case conditions. Trace lengths of theses signals must also be minimized
(<100 mm) and matched to ensure correct operation under all conditions.
13.1.2
The GMII interface passes data to and from the ZL50110/11/14 with their related transmit and receive clocks. It is
therefore recommended that the trace lengths for transmit related signals and their clock and the receive related
signals and their clock are kept to the same length. By doing this the skew between individual signals and their
related clock will be minimized.
13.1.3
Although the data rate of this interface is low the outputs edge speeds share the characteristics of the higher data
rate outputs and therefore must be treated with the same care extended to the other interfaces with particular
reference to the lower stream numbers which support the higher data rates. The TDM interface has numerous
clocking schemes and as a result of this the input clock traces to the ZL50110/11/14 devices should be treated with
care.
13.1.4
Particular effort should be made to minimise crosstalk from ZL50110/11/14 outputs and ensuring fast rise time to
these inputs.

13.2
The CPU_TA output signal from the ZL50110/11/14 is a critical handshake signal to the CPU that ensures the
correct completion of a bus transaction between the two devices. As the signal is critical, it is recommend that the
circuit shown in Figure 49 is implemented in systems operating above 40 MHz bus frequency to ensure robust
operation under all conditions.
The following external logic is required to implement the circuit:
•
•
•
•
Place series termination resistors as close to the pins as possible
Minimise output capacitance
Keep common interface traces close to the same length to avoid skew
Protect input clocks and signals from crosstalk
