FPGA(Field Programmable Gate Array)에 직렬버스(serial bus) 트랜시버(transceiver)를 내장하여 1Gpbs 이하의 소스 싱크로너스 클록(source-synchronous clock) 신호는 물론이고 3.125Gbps에 이르는 고속 직렬 신호까지 외부SerDes 칩 없이 처리할 수 있게 되었다. 따라서 SerDes 내장형 FPGA 디바이스가 백플랜 디자인의 브리지 칩으로 부상하고 있으며, I/O 연결, 기가비트 이더넷, 스토리지 연결에 이르기까지 다양한 프로토콜에 적용되고 있다. 본 고에서는 이러한 직렬 트랜시버를 내장한 FPGA 제품들에 대해서 살펴보며 그 기능과 특징에 대해서 알아보도록 한다. FPGA 기술이 발전함에 따라 FPGA의 단점으로 지적되어 오던 높은 가격, 제한된 용량, 높은 전력 소비, 낮은 성능 등의 한계가 조금씩 깨어지고 있다. 더욱이 ASIC은 0.13㎛ 이하의 미세 공정에서 마스크 비용과 설계 툴 비용이 계속해서 증가하고 있을 뿐 아니라 NRE, 패키징, 테스트 비용도 또한 증가하게 되었다. PLD 업계에서는 엄청난 규모의 대량 생산이 아니고는 ASIC제품의 경제성이 FPGA를 능가할 수 없다는 분석을 내놓고 있다[1].
