Micrel introduced a single chip programmable SERDES (Serializer/Deserializer) that supports multiple Passive Optical Network (PON) standards and rates including asymmetric Gigabit Passive Optical Network (GPON) with data rates up to 2.5 Gbps on the receive side and 1.25 Gbps on the transmit side.
Micrel’s SY87725L SERDES chip offers complete clock recovery and data retiming circuitry, along with an integrated 4-bit serial-to-parallel data converter, on the receive side. On the transmit side, it also includes a synthesizer with an integrated 4-bit parallel-to-serial data converter. Micrel said its device is targeted at BPON/GPON/GEPON/EPON applications in the growing Fiber-to-the-Home and Fiber-to-the-Premises markets. The SY87725 is currently available in volume and is priced at $9.95 for 1K quantities. http://www.micrel.com/
