85357AGI-01LF

Overview

The ICS85357I-01 is a 4:1 or 2:1 differential-to-3.3V LVPECL/ECL clock multiplexer operating up to 750MHz. It features four selectable differential CLK/nCLK inputs and one differential 3.3V LVPECL output. The device supports LVDS, LVPECL, LVHSTL, SSTL, and HCSL input levels. In LVPECL mode, VCC ranges from 3.135V to 3.465V with VEE at 0V; in ECL mode, VCC is 0V with VEE ranging from -3.135V to -3.465V. Maximum propagation delay is 1.5ns, and part-to-part skew is 415ps maximum. It operates within an ambient temperature range of -40°C to 85°C.

Feature Summary

• Configurable as a 4:1 or 2:1 multiplexer using internal pull-down resistors on select pins
• Accepts multiple differential input standards including LVDS, LVPECL, LVHSTL, SSTL, and HCSL
• Translates single-ended signals to 3.3V LVPECL levels when resistor bias is applied to the nCLKx input
• Low propagation delay of 1.5ns maximum and part-to-part skew of 415ps maximum

Applications

• Clock distribution circuits requiring low propagation delay
• Systems needing translation between various differential logic families and LVPECL
• High-speed digital designs utilizing HiPerClockS technology

Procurement Notes

Verify the specific ordering suffix (e.g., T10 for tube, R10 for reel) against current manufacturer documentation to confirm package quantity and carrier type. Confirm RoHS compliance status and lead-free designation if required by assembly specifications. Ensure the selected variant matches the required thermal resistance characteristics for the intended PCB layout.

Selection Notes

Select this component when a high-speed multiplexer capable of handling diverse differential input standards is required. Ensure the design accommodates the specific supply voltage requirements for either LVPECL or ECL operation modes. Verify that the board layout supports the necessary termination for LVPECL outputs to maintain signal integrity at frequencies up to 750MHz.
