14-BIT CONFIGURABLE REGISTERED BUFFER FOR DDR2
ICSSSTUAF32869A
The ICSSSTUAF32869A includes a parity checking function. The ICSSSTUAF32869A accepts a parity bit from the memory controller at its input pin PARIN one or two cycles after the corresponding data input, compares it with the data received on the D-inputs and indicates on its opendrain PTYERR pin (active low) whether a parity error has occurred. The number of cycles depends on the setting of C1. When used as a single device, the C1 input is tied low. When used in pairs, the C1 inputs is tied low for the first register (front) and the C1 input is tied high for the second register.
