LMK1D1216RGZT

Clock Buffers, Drivers Overview

The LMK1D1216RGZT is a low additive jitter LVDS buffer from Texas Instruments, featuring a 2:16 differential output configuration. It distributes one of two selectable clock inputs (IN0 or IN1) to 16 pairs of differential LVDS outputs (OUT0 through OUT15). The device supports input frequencies up to 2 GHz and operates with supply voltages ranging from 1.71 V to 3.465 V. Key electrical specifications include a maximum propagation delay of 575 ps, maximum output skew of 20 ps, and maximum random additive jitter of 60 fs RMS (measured at 156.25 MHz with a 12 kHz to 20 MHz integration range). It accepts universal input signal levels including LVDS, LVPECL, LP-HCSL, HCSL, CML, and LVCMOS.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'RGZT' corresponds to the specific tape-and-reel packaging variant of the LMK1D1216 in the manufacturer's current orderable addendum. Confirm that the component meets RoHS compliance requirements for the intended deployment environment. Ensure the procurement source provides valid traceability documentation consistent with Texas Instruments production standards.

Clock Buffers, Drivers Selection Notes

Select the LMK1D1216 when 16 differential LVDS outputs are required from a single clock source. Choose this device over the LMK1D1212 if higher channel count is necessary. Consider the boosted amplitude mode (AMP_SEL = 1) if driving long transmission lines or receivers requiring higher voltage swings. Verify that the input signal format matches the supported levels (LVDS, LVPECL, etc.) and that the operating temperature range (-40°C to 105°C) fits the application constraints.

Clock Buffers, Drivers Part Context

The LMK1D1216 is part of the LMK1D121x family of low additive jitter LVDS buffers, which also includes the LMK1D1212 (2:12 buffer). Both devices share similar electrical characteristics and input compatibility but differ in output count and package size. The LMK1D1216 utilizes a 48-pin VQFN (RGZ) package, whereas the LMK1D1212 uses a 40-pin VQFN (RHA) package. This family is designed for high-performance clock distribution in noise-sensitive applications.

Clock Buffers, Drivers Replacement Considerations

The LMK1D1212 serves as a lower-channel-count alternative within the same family. For direct replacement verification, consult the official Texas Instruments LMK1D121x datasheet for the complete list of orderable parts and package options.
