ICS853011BGLF

Clock Buffers, Drivers Overview

The ICS853011BGLF is a low skew, high performance 1-to-2 differential-to-2.5V/3.3V LVPECL/ECL fanout buffer from the HiPerClockS family. It accepts differential inputs including LVPECL, LVDS, CML, and SSTL, translating them to two differential LVPECL or ECL outputs. The device supports maximum output frequencies exceeding 3GHz with typical output skew of 5ps and part-to-part skew up to 130ps. Additive phase jitter is typically 0.06ps RMS. It operates on a single supply: VCC = 2.375V to 3.8V (VEE = 0V) for LVPECL mode, or VEE = -3.8V to -2.375V (VCC = 0V) for ECL mode. It is housed in an 8-lead TSSOP package.

Clock Buffers, Drivers Procurement Notes

Verify the 'G' suffix indicates the 8-lead TSSOP package (3mm x 3mm x 0.95mm). Confirm RoHS compliance status if required by specific manufacturing standards. Ensure the ordering suffix matches the desired temperature range (-40°C to +85°C). Cross-reference with original manufacturer documentation to confirm current production status.

Clock Buffers, Drivers Selection Notes

Select this component when a 1-to-2 fanout buffer is needed for LVPECL or ECL networks. It is suitable for applications requiring low skew (<130ps max) and high frequency (>3GHz). Consider the TSSOP package constraints for PCB layout. Verify input signal compatibility with LVDS, CML, or SSTL levels before implementation.

Clock Buffers, Drivers Part Context

The ICS853011 belongs to the HiPerClockS family of high-performance clock solutions originally developed by Integrated Circuit Systems, Inc. (ICS), which was later acquired by Integrated Device Technology (IDT) and subsequently Renesas Electronics. This series focuses on low skew, high-speed clock buffering and distribution.

Clock Buffers, Drivers Replacement Considerations

Pin-compatible replacements include MC100LVEP11 and SY100EP11U. Verify electrical specifications such as skew and operating voltage ranges match application requirements before substitution.

Clock Buffers, Drivers FAQ

Can the ICS853011 accept single-ended input signals?

Yes, by using resistor biasing on the nPCLK input, the differential PCLK/nPCLK pair can translate any single-ended input signal to 3.3V LVPECL levels.

What is the recommended termination for unused LVPECL outputs?

Unused LVPECL outputs can be left floating with no trace attached. Both sides of the differential output pair should either be left floating or terminated.

How does the device handle power supply configurations?

It operates in LVPECL mode with VCC = 2.375V to 3.8V and VEE = 0V, or in ECL mode with VCC = 0V and VEE = -3.8V to -2.375V.
