Micrel Announces New 2.5 Gbps GPON ONU Transceiver Solution

SAN JOSE, Calif., June 5 /PRNewswire-FirstCall/ -- Micrel Inc., (NASDAQ: MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today launched the SY87725L, 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. This product 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. The 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. An evaluation board is also available.

"The SY87725L SERDES manages all the high frequency signals in an ONU (Optical Network Unit) and is an ideal low-cost solution for a programmable or upgradeable ONU when pairing with a low cost FPGA," said Thomas S. Wong, vice president high bandwidth products for Micrel. "With the flexibility of the transceiver and the low cost of a FPGA, our customers can provide ONU solutions only limited by their imaginations."

The SY87725L has a 4-bit interface and a double data rate option is included to reduce the clock frequency. This allows the use of the lowest cost FPGA without a significant increase in I/O pins. This device also features a novel auto-align circuit that further simplifies the critical timing requirement. The part operates on a single 3.3V supply with 1W typical power consumption. The parallel 4-bit input/output interfaces feature LVDS I/O. It is available in lead-free (10mm x 10mm) 64-pin and EPAD-TQFP package options.
