HiLight Semiconductor releases 11.3-Gbps CMOS TIA

HiLight Semiconductor announced the full mass-production release of the HLR10G1, an 11.3-Gbps CMOS transimpedance amplifier (TIA) that can be used with 10-Gbps avalanche photodiodes (APDs) to provide advanced sensitivity performance. Measured sensitivities greater than -33 dBm have been achieved at bit error rates (BERs) of 1E-3, and up to -28 dBm at BERs of 1E-12, across several of the market's commercially available APDs, the company states.

The HLR10G1 is designed to be suitable for an array of limiting amplifiers and the company's 10G-PON "Combo" ICs, and it features:

· Optimization for use with a wide range of 10 Gbps APDs.

· Low power consumption (24 mA with single 3.3 V supply).

· 2-bit bandwidth adjust function for optimizing the TIA's performance with various manufacturers' APDs.

· A compact die size that HiLight says enables simple, low-cost, high-volume optical receiver assemblies.

In August, HiLight made engineering samples and reference kits for the first members of its series of CMOS "combo" ICs available, and says that its 11.3-Gbps CMOS TIA is another CMOS IC benchmark for the company (see "HiLight Semiconductor sampling HLC10Px series CMOS combo ICs").

"Having already reached the milestone of over 40Mu ICs shipped, we're pleased to announce another CMOS IC milestone - the full production release of the HLR10G1 10G TIA," said Christian Rookes, HiLight's vice president, marketing. "We are using CMOS technology to deliver high-performance yet cost-effective solutions to meet the economies of scale that the 10G-PON market requires. Our team has significant experience in this market having successfully deployed high-volume CMOS EPON and GPON chipsets previously, so we're very excited to be enabling the 10G-PON market with a fully CMOS chipset solution that also includes the HLC10P1 Asymmetric and HLC10P0 Symmetric 10G ‘Combo' ICs for ONU, in addition to the HLR10G1 TIA."
