What are the key features of LTC6957HMS-4#TRPBF?
- Differential input conditioning accepts LVPECL, LVDS, or sinusoidal clock signals for flexible source compatibility in high-speed timing systems
- 2 low-skew true outputs with less than 100 ps output-to-output skew for synchronous multi-board clock distribution
- 3 mA output current capability (Max I(ol)) in a compact 12-pin MSOP small-outline package for space-constrained clock distribution circuits
- Optimized for high-frequency clock fanout in data converters, FPGAs, and communications infrastructure requiring sub-picosecond jitter performance
What is LTC6957HMS-4#TRPBF used for?
The LTC6957HMS-4#TRPBF is designed for precision clock distribution in high-speed data acquisition systems, software-defined radio platforms, and FPGA-based digital signal processing boards where low jitter and sub-100 ps output skew are required. Its differential input stage accepts reference oscillator outputs in LVPECL or sinusoidal format, making it suitable for distributing 100 MHz to 1 GHz system clocks to multiple ADC, DAC, or FPGA clock inputs simultaneously. The MSOP-12 package and single-supply operation allow integration into compact PCB layouts for test and measurement instruments and telecommunications line card timing circuits.

Frequently Asked Questions
What input signal types does the LTC6957HMS-4#TRPBF accept for its differential clock input?
The LTC6957HMS-4#TRPBF features differential input conditioning that accepts LVPECL, LVDS, CML, and sinusoidal clock signals, providing broad compatibility with most reference oscillator output standards. This flexibility allows the device to interface directly with 100 MHz TCXO or OCXO oscillator outputs and distribute the clock to downstream FPGA and ADC devices without requiring external AC-coupling or level-shifting circuits.
How many outputs does the LTC6957HMS-4#TRPBF provide and what is the skew performance between them?
The LTC6957HMS-4#TRPBF provides 2 true output channels with ultra-low output-to-output skew, typically less than 100 ps, making it suitable for distributing a single reference clock to 2 synchronized ADC or DAC devices in data acquisition front-ends. The low skew performance ensures both outputs remain phase-aligned within tight margins critical for multi-channel simultaneous sampling systems operating at 100 MHz or higher sample rates.
In which system designs is the LTC6957HMS-4#TRPBF preferred over a standard logic buffer for clock distribution?
The LTC6957HMS-4#TRPBF is preferred over a standard logic buffer in precision timing applications where phase noise and additive jitter matter, such as software-defined radio receivers, high-speed oscilloscopes, and spectrum analyzers requiring sub-picosecond RMS jitter. A standard CMOS logic buffer introduces significant additive jitter due to supply noise sensitivity, while the LTC6957 is optimized to minimize phase noise degradation when distributing clocks at frequencies from 1 MHz to over 200 MHz.
What package is used for LTC6957HMS-4#TRPBF and how does it suit high-density timing PCB designs?
The LTC6957HMS-4#TRPBF uses a 12-pin MSOP (Mini Small Outline Package, JESD-30 R-PDSO-G12) with a body size approximately 3 mm × 3 mm and 0.65 mm pitch leads. This compact package allows clock distribution circuits to be placed very close to ADC or FPGA clock inputs on densely populated PCBs, minimizing trace length and reducing clock signal degradation in high-frequency data converter interface layouts.
