Transceiver and interface for IC package
An interconnect system includes a first circuit board, first and second connectors connected to the first circuit board, and a transceiver including an optical engine and arranged to receive and transmit electrical and optical signals through a cable, to convert optical signals received from the cable into electrical signals, and to convert electrical signals received from the first connector into optical signals to be transmitted through the cable. The transceiver is arranged to mate with the first and second connectors so that at least some converted electrical signals are transmitted to the first connector and so that at least some electrical signals received from the cable are transmitted to the second connector.
1. A transceiver comprising:
a circuit board that is configured to connect to a two-piece connector system and that includes first, second, and third lands located on the circuit board, wherein
the first lands are located on a top of the circuit board,
the second and third lands are located on a bottom of the circuit board,
the second lands are located opposite the first lands,
the third lands are located near a back end of the circuit board opposite to a front end of the circuit board with the first and second lands,
the first and second lands are configured to connect with a front connector of the two-piece connector system, and
the third lands are configured to connect with a back connector of the two-piece connector system.
2. The transceiver of claim 1 , wherein the front end of the circuit board mates with the front connector.
3. The transceiver of claim 1 , wherein the third lands engage a row of contacts on the back connector.
4. The transceiver of claim 1 , wherein the transceiver is pressed down onto the back connector and then pressed forward so that the front end of the circuit board is inserted into the front connector.
5. The transceiver of claim 4 , wherein the front end of the circuit board is pulled out of the front connector.
6. The transceiver of claim 1 , wherein high-speed signals are transmitted through the first and the second lands and low-speed signals and/or power are transmitted through the third lands.
7. The transceiver of claim 1 , wherein
the front connector is a card-edge connector and the back connector is a compression connector, and
the third lands comprise a single row of lands.
8. The transceiver of claim 3 , wherein the third lands comprise a single row of lands.
9. The transceiver of claim 1 , wherein the transceiver latches to the two piece connector system.
10. The transceiver of claim 9 , wherein the transceiver latches to the back connector.
11. The transceiver of claim 1 , further comprising a heat sink.
12. The transceiver of claim 1 , further comprising an optical engine.
13. A transceiver interconnect system comprising:
the transceiver of claim 1 ; and
a two-piece connector system including the front connector and the back connector.
14. The transceiver interconnect system of claim 13 , wherein the front connector includes a first row of contacts that engage with the first lands and a second row of contacts that engage with the second lands.
15. The transceiver interconnect system of claim 13 , wherein
the front connector is a card-edge connector, and
the back connector is a compression connector.
