Timing for Broadcom Switches

The ZL40231 is a low-additive jitter, low-power 3 × 10 LVPECL/HCSL/LVDS fanout buffer. Two inputs can accept signals in differential (LVPECL, SSTL, LVDS, HSTL, CML) or single-ended (LVPECL or LVCMOS) formats and the third input can accept a single-ended signal or can build a crystal oscillator by connecting an external crystal resonator between its XIN and XOUT pins.

The OX–502 mini OCXO combines a small footprint with high stability and reliability to support packet-based timing through excellent short-term stability. The OX–502 bridges the gap between AT cut-based TCXOs and larger OCXO designs. They are a great option for small form factor 5G base station applications.

The VCC1 XO is a quartz-stabilized square wave generator with a CMOS output. The VCC1 uses fundamental or third overtone crystals, resulting in very low jitter performance and a monolithic IC that improves reliability and reduces cost.

The ZL30733 is a feature-rich network synchronization solution with up to six independent DPLLs and five extremely low-output jitter synthesizers with IEEE^® 1588-2008 PTP stack and synchronization algorithm software modules. This solution is well suited for applications such as 5G Distributed Units (DUs), Centralized Units (CUs) and Radio Units (RUs).
