Abstract
A data transmission system includes a transmitter having a first switching re-timer and a receiver having a second switching re-timer. The first switching re-timer is configured to double a link rate per lane and halve the number of lanes, and the second switching re-timer is configured to halve the doubled link rate and double the halved number of lanes.
Claims25
A universal serial bus (USB) transmission device, comprising:
- a first interface configured to receive display port (DP) data via M lanes at a first link rate, wherein M is a switching re-timer configured to
- multiplex the DP data received via each of the M lanes into N lanes, wherein N is an integer value equal to M/2;
- and
- output the multiplexed data on each of the N lanes at a second link rate, wherein the second link rate is equal to the first link rate multiplied by M/N.
A universal serial bus (USB) reception device, comprising:
- a first interface configured to receive display port (DP) data via M lanes at a first link rate, wherein M is an integer greater than 1;
- a switching re-timer configured to
- demultiplex the DP data received via each of the M lanes into N lanes, wherein N is an integer value equal to M multiplied by 2;
- and
- output the multiplexed data on each of the N lanes at a second link rate, wherein the second link rate is equal to the first link rate multiplied by M/N.

- and
- a USB reception device, comprising:
- a second interface configured to receive the DP data output from the USB transmission device on Y lanes at the second link rate, wherein Y is an integer greater than 1;
- a second switching re-timer configured to
- demultiplex the DP data received via each of the Y lanes into Z lanes, wherein Z is an integer value equal to Y multiplied by 2;
- and
- output the multiplexed data on each of the Z lanes at the first link rate.
