1 / 20 page  1 ©2017 Integrated Device Technology, Inc. June 16, 2017 Description 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 3RD mode 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. 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. Features • 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) • Additive phase jitter, RMS: 27fs (typical) • LVPECL mode operating voltage supply range: V CC = 2.375V to 3.465V, VEE = 0V • ECL mode operating voltage supply range: V CC = 0V, VEE = -3.465V to -2.375V • -40°C to 85°C ambient operating temperature • Available in lead-free (RoHS 6) package 5 6 7 8 16 15 14 13 1 2 3 4 12 11 10 9 QA0 nQA0 QA1 nQA1 INA0 nINA0 INA1 nINA1 853S54I-01 16-Lead VFQFN 3mm x 3mm x 0.925mm package body K Package Top View Block Diagram Pin Assignment 0 1 0 1 LOOP 0 LOOP 1 SELB SELA INA0 nINA0 INA1 nINA1 QA0 nQA0 QA1 nQA1 INB nINB QB nQB Pullup/Pulldown Pulldown Pullup/Pulldown Pulldown Pullup/Pulldown Pulldown 853S54I-01 Datasheet Dual 2:1, 1:2 Differential-to-LVPECL/ ECL Multiplexer |
