HMC6832ALP5LETR

Clock Buffers, Drivers Overview

The HMC6832ALP5LETR is a low noise, 2:8 differential fanout buffer designed for clock distribution applications. It operates within a frequency range of 10 MHz to 3500 MHz and supports supply voltages from 2.375 V to 3.6 V. The device features configurable LVPECL or pseudo-LVDS outputs, with an ultralow noise floor typically reaching −165.9 dBc/Hz at 2000 MHz. It accepts CML, LVDS, LVPECL, or CMOS inputs via AC or DC coupling. Key electrical parameters include a typical propagation delay of 201 ps (LVPECL) or 207 ps (LVDS), channel skew of ±5 ps, and a core current of 56 mA.

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'LETR' against the manufacturer's ordering guide to confirm package type and reel specifications. Ensure compatibility with the 28-lead LFCSP (5 mm × 5 mm) footprint during procurement planning. Confirm that the selected variant matches the required thermal resistance and moisture sensitivity level (MSL3) ratings for the intended assembly process.

Clock Buffers, Drivers Selection Notes

Select this component when low phase noise and precise timing are critical for downstream circuits like ADCs or SERDES. Choose between LVPECL and LVDS configurations based on the target system voltage requirements; LVPECL supports both 2.5 V and 3.3 V supplies, while LVDS is limited to 2.5 V. Consider the input signal format (CML/LVDS/LVPECL/CMOS) to determine necessary coupling methods and impedance matching.

Clock Buffers, Drivers Part Context

Clock Buffers, Drivers FAQ

How is the output configuration determined?

The CONFIG pin determines the output mode. Logic 0 selects LVPECL termination, while Logic 1 or an open state (internally pulled high) selects pseudo-LVDS termination.

What is the maximum operating frequency?

The device has a wideband operating frequency range extending up to 3500 MHz (3.5 GHz).

Can the device handle single-ended inputs?

Yes, the HMC6832 supports single-ended inputs with a swing range of 0.1 V to 2 V, although it is primarily designed for differential signaling.
