1.25V/1.35V/1.5V REGISTERING CLOCK DRIVER WITH PARITY TEST AND QUAD CHIP SELECT
COMMERCIAL TEMPERATURE RANGE
Two Parity-Error Occurrences Separated by two Clock Cycles of no Error Occurrence
1 CK left out for better visibility.
The next figure shows the parity diagram with two parity-error occurrences; during chip-select and chip-deselect
modes. The diagram assumes the occurrence of both parity errors when data is clocked in at the n and n+1 input
clock cycles (PAR_IN clocked in on the n+1 and n+2 input clock cycles). Parity error in the chip-select mod is
detected, but parity error in the chip-deselect mode is ignored.
Parity-Error Occurrence In Chip-Deselect Mode
1 CK left out for better visibility.
The next figure shows the parity diagram with two parity-error occurrences; during normal operation and during
control register programming. The diagram assumes the occurrence of both parity errors when data is clocked in
at the n and n+3 input clock cycles (PAR_IN clocked in on the n+1 and n+4 input clock cycles). The data on the n+3
input clock pulse is intended for the control mode register. Parity error during control mode register programming is
detected and the parity functionality is the same as during normal operation. If a parity error occurs, the command
is ignored.
