Frequently Asked Questions
What input signal standards does the LTC6957HMS-4#PBF accept on its differential input?
The LTC6957HMS-4#PBF differential input is compatible with LVDS, LVPECL, HCSL, and sinusoidal sources. The input threshold is internally biased so that signals with amplitudes as small as 200 mV peak-to-peak can be reliably converted to the dual CMOS output levels, making it flexible for a wide range of clock source types.
How does the LTC6957HMS-4#PBF help reduce phase noise in a 100 MHz clock distribution network?
The device introduces very low additive phase noise, typically below -160 dBc/Hz at 10 kHz offset at 100 MHz, preserving the spectral purity of the input reference clock. This makes it suitable for driving ADC sampling clocks where even picosecond-level jitter degrades SFDR and SNR performance in 16-bit conversion systems.
Which package does the LTC6957HMS-4#PBF use and what are its key physical dimensions?
The LTC6957HMS-4#PBF is housed in a 12-lead MSOP package measuring approximately 3 mm x 3 mm in body size with a 0.65 mm pitch between leads. The small footprint enables tight PCB layouts in space-constrained clock distribution boards, and the lead-free, RoHS-compliant construction supports modern environmental compliance requirements.
In what supply voltage range does the LTC6957HMS-4#PBF operate?
The LTC6957HMS-4#PBF operates from a single supply voltage of 2.375 V to 3.465 V, covering the standard 2.5 V and 3.3 V rails commonly used in digital and mixed-signal systems. This range allows direct integration with FPGA I/O banks and logic circuits without requiring an additional voltage regulator.
