1. Consult Micron Technical Notes for more thorough discussions of clocking schemes.
2. Data capture is possible using only one of the two signals. CQ and CQ# clocks are optional use outputs.
3. For high frequency applications (200 MHz and faster) the CQ and CQ# clocks (for data capture) are recommended
MASTER
ASIC)
over the C and C# clocks (for data alignment). The C and C# clocks are optional use inputs.
