REVISION HISTORY Issue No. 4 Issue Date Jul 2000 Details of Change Removed section on datasheet discrepancies. Removed TU3 Inband Error from the functional discrepancies. Aligns with issue 4 of the datasheet. Aligns with Revision B of the device. Added datasheet discrepancies 2.4-2.8: TUGEN Bit Description, TUGBYP Bit Description, Device ID Revision Number, SOS Bit Description and Boundary Scan ID Change. Removed Issue 2 functional discrepancies 3.1-3.3: Device May Corrupt Data After Reset, Device May Fail to Detect FIFO Over- or Underflow Condition and Device May Fail to Recover From FIFO Over-or-Underflow Condition. Added functional discrepancy 3.2: IAIS Pin Exhibiting Boundary Condition Anomalies Added TU3 Inband Error description. Added changes to timing and operating conditions. All Input Hold Times for SCLK (19.44MHz) are changed from 1ns to 1.5ns. All Output Max Prop Delay for HSCLK (77.76MHz) is changed from 8ns to 9ns. All Output Min Prop Delay for SCLK (19.44MHz) is changed from 2ns to 3.5ns. Operating Condition for VDD3.3 is changed from 3.3V 10% to 3.3V 0.3V and the operating condition for VDD2.5 is changed from 2.5V 10% to 2.5V 0.2V. Document Creation.

FUNCTIONAL DISCREPANCIES IAIS Pin Exhibiting Boundary Condition Anomalies
2.1.1 Description The IAIS (IAIS[4:1]) pin is used for tributary AIS insertion when the pointer bypass mode is enabled in the VTPP block (i.e. tributary pointer interpreter is turned off). During the POH or fixed stuff column time-slot, the immediately preceding tributary remains selected. As a result, the corresponding AIS status register maybe updated erroneously if the AIS assertion via the IAIS pin does not persist over the POH or fixed stuff column. 2.1.2 Software Workaround The software workaround is implemented by setting the IPAIS register bit associated with a particular tributary in the VTPP TSB if and when an AIS condition needs to be generated in that tributary. 2.1.3 Hardware Workaround The hardware workaround is implemented by extending or holding the AIS assertion of tributary time-slot immediately preceding the POH or fixed stuff column until the next valid tributary time-slot. The holding period may extend across transport overhead columns of the SONET/SDH frame.
