STLVD111BFR

Clock Buffers, Drivers Overview

The STLVD111BFR is a programmable low voltage 1:10 differential LVDS clock driver designed for high-performance clock distribution in 2.5V systems. It features an 11-bit shift register and control register to enable or power off individual output channels and select between two differential clock inputs (CLK0/CLK1). The device guarantees low skew performance, with a maximum part-to-part skew of 100ps and bank skew of 50ps. It supports signaling rates exceeding 622MHz, operates within a VCC range of 2.375V to 2.625V, and includes fail-safe features for open, short, and terminated input conditions.

Clock Buffers, Drivers Feature Summary

• Low skew design with 100ps part-to-part skew and 50ps bank skew
• Programmable 1:10 differential LVDS driver with 11-bit serial shift register
• High signalling rate capability exceeding 622MHz
• Supports open, short, and terminated input fail-safe states

Clock Buffers, Drivers Applications

• High performance clock distribution in 2.5V systems
• Distributing low skew clocks across backplanes
• Board-level clock distribution networks

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'BFR' corresponds to the TQFP32 package in tape and reel packaging containing 2400 parts per reel. Confirm the operating temperature range is -40°C to 85°C. Ensure the application environment maintains the recommended supply voltage of 2.375V to 2.625V for optimal electrical characteristics.

Clock Buffers, Drivers Selection Notes

Select this component when low skew is critical for clock distribution. The device requires a 2.5V nominal supply voltage. Designers must account for the 11-bit serial configuration process via the CK, SI, and EN pins. The device supports both programmed mode for selective channel activation and standard mode where all outputs are enabled based on the SI pin state.

Clock Buffers, Drivers Part Context

The STLVD111BFR belongs to the STLVD111 family of programmable LVDS clock drivers manufactured by STMicroelectronics. It is housed in a TQFP32 package. The 'BFR' suffix indicates the specific packaging format (Tape & Reel) and temperature grade (-40 to 85 °C), distinguishing it from other variants like the bulk-packaged STLVD111.
