Skyworks Solutions, Inc. launched its latest portfolio of jitter attenuators for high-speed networking, communications and data centre equipment forming the backbone of today's internet infrastructure. These new products are designed to meet the performance requirements of high-speed networks deployed to carry 5G traffic and support new applications like AI and edge computing. The new Si536x product family complements Skyworks' current Si539x jitter attenuating clocks to suit the specific timing needs of designers and vendors.

Increasing demand for data bandwidth is driving the need for 400G/600G/800G+ Ethernet links using high-speed 56G/112G/224G PAM-4 SerDes and coherent optical technologies for internet infrastructure and data centre environments. The Dell'Oro Group forecasts that these data rates currently comprise half of the total Ethernet data centre, with 800G expected to dominate by 2025.1 These high-speed systems require multiple clocks at different frequencies, signaling formats and voltage levels with ultra-low jitter. Skyworks' Si536x family offers the following features and benefits: Up to 18 outputs with any combination of frequencies up to 2.75GHz and a wide range of selectable output formats, including LVPECL, LVDS, CML, HCSL and LVCMOS.

These output thresholds are also customizable to support chipsets that have non-standard formats. Seamless input clock management with exceptional input reference clock switching performance, including internal and external hitless switching modes of operation, supporting 35 ps and 75 ps phase transients respectively. Full suite of clock quality metrics and alarms providing full visibility to clock fault monitoring.

Best-in-class < -90dB power supply rejection, enabling designers to reduce noise filtering components leading to a more cost-efficient solution and simplified bill of materials. In-circuit reconfigurability enabling output frequency changes on the fly system downtime.
