Mindspeed Technologies Inc., a supplier of semiconductor solutions for network infrastructure applications, announced the first commercially available 10 Gigabit Ethernet Passive Optical Network (10G-EPON) burst-mode receiver chipset.
Mindspeed’s 10G burst-mode, dual-rate transimpedance amplifier (TIA) and burst-mode, multi-rate limiting amplifier combine in a system for 10G-EPON Optical Line Terminals (OLTs) that is backward-compatible with existing GEPON designs.
“Mindspeed’s breakthrough solution will accelerate the adoption of 10G-EPON networks by enabling multi-service access equipment to handle higher data rates and more broadband users,” says Hasnain Bajwa, senior vice president and general manager of the lightspeed connectivity solutions (LCS) business unit at Mindspeed Technologies. “Our dual-rate burst-mode receiver solution is compatible with earlier gigabit-rate, and leverages our extensive experience in TIAs and limiting amplifiers to deliver a proven, high-value platform for next-generation equipment design.”
The M02138 TIA features dynamic rate selection with fast response times in burst-mode 10Gbps and 1Gbps operation, as well as includes burst-mode photocurrent monitoring with a combination of accuracy and output settling time that exceeds OLT requirements. The device is optimized for 10.3Gbps/1.25Gbps performance and can be assembled in a cost-effective standard 5-pin or 6-pin receiver or bi-directional optical subassembly (ROSA/BOSA).
The TIA’s companion, the M02142, is a high-performance, 11.3 Gbps limiting amplifier that includes integrated fast loss of signal (LOS) detection and is well suited for 10G-EPON burst-mode applications. The low-power device provides input sensitivity of 3 millivolts peak-to-peak (mVpp) at full data rate and, with its wide input dynamic range, can accept up to 1.6 volts peak-to-peak (Vpp) differential input voltage. Fast output settling time and dynamic rate selection are supported for 10G-EPON OLT applications.
Mindspeed is collaborating with Cyoptics to create a receiver module for customers using its burst-mode TIA. Cyoptics’ ROSA combines Mindspeed’s M02138 with Cyoptics’ avalanche photodiode (APD).
“This collaboration combines Mindspeed’s expertise in high-performance TIAs with Cyoptics’ leadership in the monolithic and hybrid integration of optical components into sub-assemblies,” says Kou-Wei Wang, vice president and general manager for OEM Business with Cyoptics. “Mindspeed’s burst mode receiver is the key design block for our 10G-EPON OLT solution and we are excited to be working with Mindspeed to offer our customers this critical ingredient for 10G-EPON deployment.”
Both the M02138 TIA and M02142 limiting amplifier are compliant with IEEE802.3av 10G-EPON specifications, and en able backward-compatibility with GE-PON burst-mode systems. The M02138 TIA is supplied in bare die waffle packs and the M02142 is packaged in a 3x3mm quad flat no lead (QFN) package. Both devices are sampling now.
