What are the key features of LTC6957IDD-1#PBF?
- Dual LVPECL outputs with ultra-low additive phase noise enabling high-integrity clock distribution in RF and data-converter systems
- Differential input conditioning accepts LVPECL, LVDS, or sine-wave clock sources, providing versatile signal-level conversion in a single IC
- 12-pin DFN package with matched propagation delays on both outputs minimizing clock skew below 50 ps in dual-channel clock trees
What is LTC6957IDD-1#PBF used for?
The LTC6957IDD-1#PBF is designed for high-performance clock distribution networks in communications, test-and-measurement, and data-converter systems where additive jitter must remain below 100 fs RMS. It converts differential or single-ended clock inputs to dual LVPECL outputs, making it suitable for driving high-speed ADC and DAC sample clocks simultaneously. The device is also used in FPGA reference-clock fanout buffers and frequency synthesizer output stages where phase noise preservation is critical.

Frequently Asked Questions
What output logic standard does LTC6957IDD-1#PBF use and how does it benefit high-speed data-converter clocking?
The LTC6957IDD-1#PBF provides 2 LVPECL differential outputs. LVPECL's fast edge rates and low-impedance drive help minimize additive jitter below 100 fs RMS when distributing sample clocks to 12-bit to 16-bit ADCs operating at 500 MHz to 3 GHz, preserving SNR in high-dynamic-range digitizer designs.
Which input signal types does LTC6957IDD-1#PBF accept and how does differential input conditioning reduce noise sensitivity?
Its differential input conditioning accepts LVPECL, LVDS, HCSL, and sine-wave inputs with amplitudes down to a few hundred millivolts. By using a differential front end, the device rejects common-mode noise and power-supply coupling that would degrade phase noise in single-ended clock buffer designs.
How does the matched dual-output architecture of LTC6957IDD-1#PBF help when driving two separate ADC channels from one reference clock?
The 2 LVPECL outputs are internally matched to within 50 ps of propagation delay, ensuring both ADC channels receive clock edges at nearly identical times. This tight output-to-output skew prevents aperture mismatch between channels in dual-ADC interleaved sampling systems operating above 1 GHz.
