Datasheet

General Description

Features

The 853S54I-01 is a 2:1/1:2 Multiplexer. The 2:1 Multiplexer

allows one of 2 inputs to be selected onto one output pin and the

1:2 MUX switches one input to one of two outputs. This device

may be useful for multiplexing multi-rate Ethernet PHYs which

have 100Mbit and 1000Mbit transmit/receive pairs onto an optical

SFP module which has a single transmit/receive pair. A 3^RDmode

allows loop back testing and allows the output of a PHY transmit

pair to be routed to the PHY input pair. For examples, please refer

to the Application Block diagrams on pages 2-3 of the data sheet.

• Dual 2:1, 1:2 MUX

• Three LVPECL output pairs

• Three differential clock inputs can accept: LVPECL, LVDS, CML

• Loopback test mode available

• Maximum output frequency: 2.5GHz

• Propagation delay: 550ps (maximum)

• Part-to-part skew: 275ps (maximum)

The 853S54I-01 is optimized for applications requiring very high

performance and has a maximum operating frequency in 2.5GHz.

The device is packaged in a small, 3mm x 3mm VFQFN package,

making it ideal for use on space-constrained boards.

• Additive phase jitter, RMS: 27fs (typical)

• LVPECL mode operating voltage supply range:

_CC= 2.375V to 3.465V, V_EE= 0V

• ECL mode operating voltage supply range:

_CC= 0V, V_EE= -3.465V to -2.375V

• -40°C to 85°C ambient operating temperature

• Available in lead-free (RoHS 6) package
