Single-ended signal equalization with a programmable 1-tap decision feedback equalizer |
摘要 |
An apparatus includes a first circuit and a second circuit. The first circuit may be configured to (i) receive a sequence of input values that have been carried on a single-ended line of a data bus coupled to a memory channel, (ii) slice a previous input value of said sequence of input values to generate a previous output value, (iii) slice a current input value of said sequence of input values to generate a current output value, and (iv) present said current output value on a differential line. The previous input value generally precedes said current input value in said sequence of input values. The second circuit may be configured to decode said previous input value based on a tap coefficient value to generate a plurality of feedback values suitable to reduce an inter-symbol interference in said current input value caused by said previous input value. |

1. An apparatus comprising:
a first circuit configured to (i) receive a sequence of input values that have been carried on a single-ended line of a data bus coupled to a memory channel, (ii) slice a previous input value of said sequence of input values to generate a previous output value, (iii) slice a current input value of said sequence of input values to generate a current output value, and (iv) present said current output value on a differential line, wherein said previous input value precedes said current input value in said sequence of input values; and a second circuit configured to decode said previous input value based on a tap coefficient value to generate a plurality of feedback values suitable to reduce an inter-symbol interference in said current input value caused by said previous input value. |
