XRT91L31IQ-F Overview
PQFP comes with the case. 64 terminations are found in it. Voltage 3.3V is provided by the part. To run 260, we utilize this part's peak reflow temperature. There is a maximum frequency for normaloperation of 622.08MHz. Circuits application is recommended to mount Circuits application wCircuits applicationh Surface Mount. 64 pins are provided on the device. The board includes 64 pins. Temperatures below -40°C are not permitted for this device. Temperatures should not exceed 85°C. 3.3V is the recommended supply voltage. Voltage 3.465V is applied to this part. A supply voltage greater than 3.135V is needed to keep the device operating. Device uses telecom IC type ATM/SONET/SDH TRANSCEIVER. ATM;SDH;SONET is appropriate for the part.
