LMK1D2102LRGTT

Clock Buffers, Drivers Overview

The LMK1D2102LRGTT is a low additive jitter LVDS clock buffer manufactured by Texas Instruments. It features five differential LVDS outputs and accepts universal input signals including LVDS, LVPECL, HCSL, CML, and LVCMOS. The device operates within a supply voltage range of 1.71 V to 3.465 V and supports maximum input frequencies up to 250 MHz. Key electrical parameters include a maximum propagation delay of 575 ps and a typical phase noise floor of -164 dBc/Hz at 156.25 MHz. It is housed in a 16-pin VQFN package and functions within an industrial temperature range of -40°C to +105°C.

Clock Buffers, Drivers Feature Summary

• Ultra-low additive jitter performance with less than 60 fs RMS (max) at 156.25 MHz across 12 kHz to 20 MHz bandwidth
• Universal input compatibility supporting LVDS, LVPECL, LP-HCSL, HCSL, CML, and LVCMOS signal levels
• Configurable output amplitude via AMP_SELA/AMP_SELB pins for standard LVDS (350 mV) or boosted LVDS (500 mV)
• Integrated fault-safe input functionality with thermal hysteresis to prevent random oscillation without input signals

Clock Buffers, Drivers Applications

• Telecommunications infrastructure requiring precise clock distribution
• High-speed data acquisition systems
• Wireless base station timing applications

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'RGTT' corresponds to the 16-pin VQFN package and reel/cut-tape packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design specifications align with the 1.71 V to 3.465 V operating voltage range and -40°C to +105°C temperature limits.

Clock Buffers, Drivers Selection Notes

Select this component when low skew and ultra-low jitter are critical for distributing a single clock source to multiple LVDS loads. The dual-bank architecture allows independent control of output groups via enable pins. Consider the 575 ps maximum propagation delay and 20 ps maximum output skew for timing budget calculations in high-frequency designs.

Clock Buffers, Drivers Part Context

The LMK1D2102LRGTT belongs to the LMK1D210xL family of dual-bank LVDS buffers. This series includes variants with different output counts, such as the LMK1D2104L (4-channel), LMK1D2106L (6-channel), and LMK1D2108L (8-channel). All members share similar low-jitter characteristics and universal input capabilities tailored for high-performance clock distribution networks.

Clock Buffers, Drivers Replacement Considerations

Direct functional substitutes within the same family include the LMK1D2104L for higher channel density. Cross-family replacements like the CDCLVP2102 offer LVPECL outputs rather than LVDS. Verify pinout compatibility and output drive requirements when considering alternative Texas Instruments clock buffer models.
