DATA SHEET

General Description

Features

The ICS853S54I is a dual 2:1 and 1:2 Multiplexer. The 2:1 Multiplex-

er 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 is

useful for multiplexing multi-rate Ethernet PHYs which have 100 M

bit and 1000 bit transmit/receive pairs onto an optical SFP module

which has a single transmit/receive pair. See Application Section for

further information.

• Three differential LVPECL output pairs

• Three differential LVPECL clock inputs

• PCLKx/nPCLKx pairs can accept the following differential input

levels: LVPECL, LVDS, CML

• Maximum output frequency: 2.5GHz

• Part-to-part skew: 200ps (maximum)

• Propagation delay: QA, nQA: 450ps (maximum)

The ICS853S54I is optimized for applications requiring very high

performance and has a maximum operating frequency of 2.5GHz.

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

making it ideal for use on space-constrained boards.

QBx, nQBx: 420ps (maximum)

• LVPECL mode operating voltage supply range:

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

• ECL mode operating voltage supply range:

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

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

• Available in lead-free (RoHS 6) packaging
