Frequently Asked Questions
How does LFSPXO018077's 25 MHz output support Ethernet PHY clock requirements?
The LFSPXO018077 provides a 25 MHz HCMOS clock output directly compatible with IEEE 802.3 Ethernet PHY reference clock inputs, which typically require 25 MHz ±50ppm. Its 50pF output load rating and 10 ns maximum fall time ensure clean signal integrity for 10/100 Mbps Ethernet applications without additional buffer stages.
What frequency stability does LFSPXO018077 provide and how does it affect network synchronization?
The LFSPXO018077 offers ±50ppm frequency stability over its operating range. For a 25 MHz clock, this means frequency deviation of at most 1250 Hz from nominal, which is within acceptable bounds for standard Ethernet and UART communication protocols. Tighter stability oscillators should be selected only when sub-10ppm precision is required.
For a compact IoT gateway PCB, how does the LFSPXO018077 ceramic SMD package simplify layout?
The LFSPXO018077 comes in a ceramic surface mount package that eliminates the need for an external crystal and load capacitors typically required with passive crystals. This integrated oscillator solution reduces component count by at least 3 parts, saves board area, and simplifies routing of the 25 MHz clock trace in space-constrained IoT gateway designs.
What is the output type of LFSPXO018077 and which logic families is it compatible with?
The LFSPXO018077 uses an HCMOS output, compatible with 3.3 V and 5 V CMOS logic families including HC, HCT, and ACT series devices. Its 50pF output load capacity supports driving multiple logic gate inputs simultaneously, making it suitable for distributing a 25 MHz clock to several ICs on a shared clock bus.
