3 Specifications & Additional Information 8B/10B Code This section proides information about the data and control codes for Stratix II GX deices. Code Notation The 8B/10B data and control codes are referred to as Dx.y and Kx.y, respectiely. The 8-bit byte (H G F E D C B A, where H is the MSB and A is the LSB) is broken up into two groups, x and y, where x is the fie lower bits (E D C B A) and y is the upper three bits (H G F). Figure 6 1 shows the designation for 3C hex. Figure 6 1. Sample Notation for 3C hex y = 1 x = 28 D28.1 = (3C hex) H G F E D C B A There are 256 Dx.y and 12 Kx.y alid 8-bit codes. These codes hae two 10-bit equialent codes associated with each 8-bit code. The 10-bit codes hae either a neutral disparity or a non-neutral disparity. With neutral disparity, two neutral disparity 10-bit codes are associated with an 8-bit code. With non-neutral disparity 10-bit code, a positie and a negatie disparity code are associated with the 8-bit code. The positie disparity 10-bit code is associated in the RD- column. The negatie disparity 10-bit code is associated in the RD+ column. Disparity Calculation The running disparity is calculated based on the sub-blocks of the 10-bit code. The 10-bit code is diided into two sub blocks, a 6-bit sub-block (abcdei) and a 4-bit sub-block (fghj), as shown in Figure 6 2. Figure Bit Grouping of 6-bit and 4-Bit Sub-Blocks 10-Bit Code D28.1 = (3C hex) j h g f i e d c b a 0 4-Bit Block 6-Bit Block Altera Corporation 6 3 October 2007 Stratix II GX Deice Handbook, Volume 2

4 8B/10B Code The running disparity at the beginning of the 6-bit sub-block is running disparity at the end of the preious 10-bit code. The running disparity of the 4-bit sub-block is the running disparity of the end of the 6-bit sub-block. The running disparity of the end of the 4-bit sub-block is the running disparity of the 10-bit code (refer to Figure 6 3). Figure 6 3. Running Disparity Between Sub-Blocks 10-Bit Code D28.1 = (3C hex) j h g f i e d c b a 0 4-Bit Block 6-Bit Block The running disparity calculation rules are as follows: The current running disparity at the end of a sub-block is positie if any of the following is true: The sub-block contains more ones than zeros The 6-bit sub-block is 6'b The 4-bit sub-block is 4'b0011 The current running disparity at the end of a sub-block is negatie if any of the following is true: The sub-block contains more zeros than ones The 6-bit sub-block is 6'b The 4-bit sub-block is 4'b1100 If those conditions are not met, the running disparity at the end of the sub-block is the same as at the beginning of the sub-block.
