Title

Arria GX Device Handbook: Known Issues

Description

Issue 10006612, Volume 1, Chapter 4 "DC and Switching Characteristics" Version 2.0

Note 3 of Table 4-115 does not have the correct VCO frequency specification.  It should read as follows:

(3) The input clock frequency and the W factor must satisfy the following fast PLL VCO specification: 150 <= input clock frequency × W <= 840.

Issue 10006613, Volume 2, Chapter 5 "PLLs in Arria GX Devices" Version 1.2

There are two locations that show the incorrect VCO operating frequency of the PLL.

Note 5 of Figure 5-6 should read as follows:

(5) If the design enables this ÷2 counter, the device can use a VCO frequency range of 150 to 420 MHz.

Pages 5-33 through 5-34 should state "You should choose the secondary clock frequency so the VCO operates within the recommended range of 300 to 840 MHz."

Issue 10003010, Volume 1, Chapter 2 "Arria GX Architecture" Version 1.3

Note 3 in table 2-25 states the following for the LVDS VCCIO requirements:

"VCCIO is 3.3 V when using this I/O standard in input and output column clock pins (in I/O banks 3, 4, 7, 8, 9, 10,11, and 12)."

This note should say: "LVDS input and output operations in I/O banks 9-12 require 3.3V for operation.  These banks are powered by the VCC_PLL[5,6,11,12]_OUT pins.  LVDS input operations are supported on the dedicated clock pins in I/O banks 3,4,7, and 8 which are powered by VCCINT."

Resolved Issues
