SEPTEMBER 28, 2006 -- Phyworks' (search for Phyworks) release of the PHY2078 broadens its product group offering of FTTx burst-mode laser drivers and limiting amplifiers. The PHY2078 is designed for the higher 2.5-Gbit/sec GPON ITU G.984.2 standard.
The PHY2078 can be combined with a microcontroller to enable module vendors to support digital diagnostic monitoring (DDM), allowing the key performance parameters of the device to be monitored throughout its lifetime in compliance with the SFF 8472 standard. The PHY2078 can also be used in triplexer applications where the DDM software enables monitoring of the video path optical input power, video amplifier gain control, and video path RF power sensing.
The PHY2078 encompasses features such as an on-chip state machine, a digitally controlled automatic power control (APC) loop to accurately control the Laser transmission characteristics, a high-sensitivity receive path with user-programmable filter characteristics, and very low cross talk.
The PHY1095 and PHY1097 transimpedence amplifiers (TIAs) complement the transceiver ICs by offering the user economical efficiency through exceptionally high sensitivity and low noise, the company says. The devices offer compatibility to the GPON and GEPON markets and are capable of high-sensitivity performance without the added cost of an avalanche photodiode (APD) circuit, which would typically add up to $20 to the complete module.
The PHY1097 is designed for GEPON and GPON operating at up to 2.5 Gbits/sec. The device reaches sensitivity of -29 dBm and input referred noise of 150 nA.
The PHY1095, which operates at up to 1.25 Gbits/sec, servicing the GEPON sector of the market, also reaches -32-dBm sensitivity coupled with 60 nA of input referred noise.
Both devices offer overload levels of +4 dBm, selectable RSSI output current direction, and data polarity for ease of module design and manufacture.
On the announcement of the completion of both GPON/BPON and GEPON chip sets Stephen King, Phyworks CEO, commented, "We are confident the performance of these products is market leading. Having gained a significant number of key design wins for the PHY1078 GEPON transceiver and TIAs in both the U.S. and Asian markets, we now feel we have the most complete and technically advanced solution in the industry."
Brad Weaterton, Phyworks director of marketing, added, "Phyworks are pleased to be able to bring such high-performance products to the market. We continue to dedicate resources to R&D and fully supporting our customers."
The PHY1078 and PHY2078 are available immediately in RoHS-compliant 5x5 QFN packages. The PHY1095 and PHY1097 TIAs are available as bare die or integrated in ROSAs.
Phyworks transceiver and TIA complete chipset solutions are available from $4 in volume.
Transceiver reference designs and DDM software are also available immediately.
