The present invention discloses a receive data equalization apparatus. A delay-compensating calculation circuit retrieves training data groups of a training data signal to retrieve total delay amount, generate signed compensation amounts according to a relation among training data contents of training data in each of the training data groups to generate total compensation amount accordingly, and solve equations that correspond total delay amount of the training data groups to the total compensation amount to obtain each of the compensation amounts. A receive data equalization circuit receives the compensation amounts and retrieves a receive data group in a receive data signal, generate signed receive compensation amounts according to a relation among receive data contents of receive data in the receive data group to generate a total receive compensation amount accordingly to perform equalization on a terminal edge of the receive data group according to the total receive compensation amount.

Received data equalization apparatus and method

The invention discloses a low voltage differential signal (LVDS) receiver, which is realized in an integrated circuit. The LVDS receiver includes: an input stage circuit receiving a full-range common-mode voltage and converting it into a current signal; a current source circuit coupled to the input stage circuit to provide a current source; and a current mirror circuit coupled the input stage circuit and the current source circuit to provide several bias voltage signals for the current source circuit and output a voltage signal to a buffer.
