VSC8479YHQ-01

9.95 Gbps to 11.3 Gbps 16-bit Transceiver with 10G-EPON Burst Mode Support. The VSC8479-01 is the industry’s first comprehensive 10G-EPON burst mode transceiver solution with a fast-locking, integrated clock and data recovery unit (CDR) and clock multiplier unit (CMU). The VSC8479-01 device delivers industry-leading power, performance, programmability, feature integration, and cost-effective packaging ideal for even the most price-sensitive applications, such as PON and cost-down designs. Targeted for 300-pin multisource agreement (MSA) modules and DWDM line card applications, the VSC8479-01 is also suitable for XFP/SFP+ motherboards with its proven interoperability with all major module vendors. Burst mode capability supports 10G-EPON optical line terminal (OLT) units, and continuous mode operation supports optical network units (ONUs). The VSC8479-01 is the first 10G transceiver to meet and exceed the 10G-EPON IEEE P802.3av/D3.0 Draft standard for burst mode performance. The Rx path features a high-sensitivity receiver with programmable VGA and input bandwidth equalization (EQ) for stressed input data eye compensation, and can acquire 10G-EPON data in under 100 ns. An external post amplifier is not required for most applications. The high-speed output is swing- and pre-emphasis-programmable to support an array of laser driver and XFI/SFI host ASIC applications. The VSC8479-01 device supports all features, functions, and clock modes required for 300-pin MSA transponder module full compliance. All loopback modes are supported with multiple line timing clock modes. Low power dissipation enables 300-pin MSA module vendors to provide performance and functionality advantages, while dropping the overall power dissipation in existing modules. Highly flexible reference clock source selection and reference clock clean-up support schemes minimize external circuitry. A selectable two-wire serial or serial peripheral interface (SPI) provides full microcon
