LMK00804BPW

Clock Buffers, Drivers Overview

The LMK00804BPW is a low-skew clock buffer and fanout distributor manufactured by Texas Instruments. It features a single input to four output configuration with a maximum operating frequency of 350 MHz. The device accepts multiple differential and single-ended input formats, including LVDS, LVPECL, HCSL, LVHSTL, SSTL, LVCMOS, and LVTTL. Outputs are provided in LVCMOS or LVTTL logic levels. It operates on a single 3.3V supply (3.135V to 3.465V) and is housed in a 16-TSSOP package with a width of 4.40mm. The component supports an industrial temperature range from -40°C to 85°C.

Clock Buffers, Drivers Feature Summary

• Supports diverse input standards: LVDS, LVPECL, HCSL, LVHSTL, SSTL, LVCMOS, and LVTTL
• Provides 1:4 fanout distribution with LVCMOS/LVTTL outputs
• Low skew performance optimized for high-speed clock distribution up to 350 MHz
• Single 3.3V power supply operation

Clock Buffers, Drivers Applications

• Clock distribution networks for high-speed digital systems
• Fanout buffering for FPGA and ASIC clock inputs
• System timing synchronization in telecommunications equipment
• Data converter clock generation and distribution

Clock Buffers, Drivers Procurement Notes

Verify the suffix 'PW' indicates a tube packaging format distinct from the 'PWR' tape-and-reel variant. Confirm the specific lot marking and date code against the manufacturer's latest production notices. Ensure the 16-TSSOP footprint matches the PCB design guidelines provided in the official datasheet. Check for RoHS3 compliance status as per current environmental declarations.

Clock Buffers, Drivers Selection Notes

Select this component when a single source clock must be distributed to four destinations requiring LVCMOS or LVTTL interfaces. It is suitable for replacing older fanout buffers if input compatibility with LVDS or LVPECL is required. Verify that the 3.3V supply voltage aligns with the system power architecture. Consider the 16-TSSOP package constraints regarding thermal dissipation and board space availability.

Clock Buffers, Drivers Part Context

The LMK00804B belongs to the LMK0080x family of low-noise, low-skew clock buffers. This family is designed for jitter-cleaned clock distribution in complex digital systems. The 'B' suffix typically denotes a specific revision or enhanced performance characteristic within the series compared to earlier versions like the LMK00804.

Clock Buffers, Drivers Replacement Considerations

Direct pin-to-pin replacements may include other LMK0080x variants such as LMK00804BPWR, noting the packaging difference. Cross-reference with similar 1:4 fanout buffers from other manufacturers only if input/output voltage levels and pin configurations are identical.
