MAX9317AECJ+

Clock Buffers, Drivers Overview

The MAX9317AECJ+ is a low-skew, dual 1-to-5 differential clock and data driver manufactured by Analog Devices Inc./Maxim Integrated. It accepts LVPECL or LVDS inputs and reproduces the signal on five separate LVDS outputs per channel. Designed for 2.5V systems, it operates from a 2.375V to 2.625V supply. The device features guaranteed 1.0GHz operation, 5ps output-to-output skew, and internal 50Ω input termination resistors. It is housed in a 32-pin LQFP (7x7mm) package and supports an operating temperature range of -40°C to +85°C.

Clock Buffers, Drivers Procurement Notes

Verify the component matches the specific 'A' variant which includes internal 50Ω input termination resistors, distinct from the standard MAX9317. Confirm the suffix 'ECJ+' corresponds to the 32-LQFP (7x7mm) package and RoHS compliance. Ensure the voltage rating aligns with 2.5V system requirements rather than 3.3V variants.

Clock Buffers, Drivers Selection Notes

Select the MAX9317AECJ+ when internal input termination is required to reduce external component count in 2.5V designs. Choose this over the MAX9317B/C if the system operates at 2.5V rather than 3.3V. Verify that the LVPECL input level requires connecting V_T_ pins to V_CC - 2V for proper termination configuration.

Clock Buffers, Drivers Part Context

This part belongs to the MAX9317 family of low-skew differential drivers. The 'A' designation indicates the inclusion of internal 50Ω input termination resistors. The 'ECJ' suffix specifies the 32-pin Thin QFP/TQFP package. It is pin-compatible with ON Semiconductor’s MC100EP210S.

Clock Buffers, Drivers Replacement Considerations

The datasheet explicitly states the MAX9317A is pin compatible with ON Semiconductor’s MC100EP210S.
