Semtech 发布首款 XGSPON 芯片组

Best-in-class optical solutions offer improved technical and commercial performance

Shenzhen at CIOE 2019., Sept. 3, 2019 – Semtech Corporation (Nasdaq: SMTC) a leading supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, today announced production availability of the GN7153B combo chip and the GN7055B multi-rate burst mode transimpedance amplifier (TIA) for XGSPON Optical Line Terminals (OLTs).

“XGSPON will bring a new generation of faster optical broadband services for home and business to the largest sector of the PON market,” said Dr. Timothy Vang, Vice President of Marketing and Applications for Semtech’s Signal Integrity Products Group. “Our chipset contributes to that growth by bringing high performance and low cost.”

The GN7153B is a combo chip supporting OLT transmit and receive signals in a fully integrated solution. On the receive side, the GN7153B supports both XGPON (2.5G) and XGSPON (2.5G/10G) signals, while the transmit data path features Semtech’s proven 10G EML driver with ClearEdge® CDR technology to effectively reset the signal jitter budget. Transmit path optimization can be accomplished through an I2C programmable PLL loop bandwidth control and a variety of jitter filter modes. The EML driver includes eye-shaping features and an Automatic Power Control (APC) loop to deliver best-in-class transmit eye quality. The burst mode receive data path includes a multi-rate 2.5G/10G limiting amplifier with a fast burst mode signal detect function, integrated discharge circuit and reset for short settling time.

Semtech 的高灵敏度突发模式 TIA (GN7055B) 专为 XGSPON OLT 应用而设计。突发模式 TIA 使用外部复位信号，满足 XGSPON 2.5G 和 10G 的收敛时间和突发动态范围要求。该器件具有快速自动增益控制 (AGC) 环路，可在突发模式应用中实现高动态范围。GN7055B 以裸芯片形式提供，支持工业温度范围并使用单个 3.3V 电源。
