Silicon Labs has introduced a new family of small form-factor, high-performance crystal oscillators (XOs) and voltage-controlled crystal oscillators (VCXOs) for applications that require low jitter and frequency-flexible clock synthesis.
The Si54x/6x Ultra Series XO/VCXOs deliver jitter performance as low as 80 femtoseconds (fs) for integer and fractional frequencies across the entire operating range, providing outstanding jitter margin for demanding applications including data centre interconnect, optical transport, broadcast video and test/measurement. These new products are available with single, dual, quad and I2C-programmable frequency options in an industry-standard 2.5×3.2mm package footprint, making them ideal for space-constrained designs that require a mix of different frequencies.
Ideal for high bandwidth, high-density line cards and small form factor optical modules
Increasing demand for network bandwidth and faster data rates are driving the need for higher speed 400/600/800G optical/Ethernet ports and higher density line cards. With telco and data center applications accelerating 400G deployments, the optical module market is migrating from CFP designs to smaller form factor QSFP-DD, OSFP and CFP2 solutions to help ease the industry transition to higher bandwidth, higher density line cards. These applications require low jitter, highly reliable timing solutions to optimize system bit-error rates and ensure high system availability.
Durable operation in a small footprint
The Si54x/6x are an ideal solution for 400/600/800G coherent optics and 56G/112G SerDes clocking in optical modules and line cards that require high performance in a small footprint. The devices guarantee ±20 ppm operation over a 20-year operating life, making them ideal for long-life cycle applications. All power supply filtering is integrated inside the device, eliminating discrete components that often consume as much PCB footprint as the XO itself. Silicon Labs’ Si54x/6x are drop-in compatible with traditional oscillators while providing <2 week lead times for custom frequencies.
