ECHO READ CLOCK (ERCLK)
The Echo Read Clock output is provided in both HSTL and LVTTL mode,
selectable via RHSTL. The ERCLK is a free-running clock output, it will always
follow the RCLK input regardless of
REN and RCS.
The ERCLK output follows the RCLK input with an associated delay. This
delay provides the user with a more effective read clock source when reading
data from the Qn outputs. This is especially helpful at high speeds when
variableswithinthedevicemaycausechangesinthedataaccesstimes. These
variations in access time maybe caused by ambient temperature, supply
voltage, device characteristics. The ERCLK output also compensates for any
tracelengthdelaysbetweentheQndataoutputsandreceivingdevicesinputs.

the data outputs. Note, that ERCLK is guaranteed by design to be slower than
the slowest Qn, data output. Refer to Figure 4, Echo Read Clock and Data
Output Relationship, Figure 28, Echo Read Clock & Read Enable Operation
and Figure 29, Echo RCLK & Echo
REN Operation for timing information.
ECHO READ ENABLE (
EREN)
The Echo Read Enable output is provided in both HSTL and LVTTL mode,
selectable via RHSTL.
The
EREN output is provided to be used in conjunction with the ERCLK

DATA OUTPUTS (Q0-Qn)
(Q0-Q35) are data outputs for 36-bit wide data, (Q0 - Q17) are data outputs
for 18-bit wide data or (Q0-Q8) are data outputs for 9-bit wide data.

NOTES:
1.
REN is LOW.
2. tERCLK > tA, guaranteed by design.
3. Qslowest is the data output with the slowest access time, tA.
4. Time, tD is greater than zero, guaranteed by design.
