TS2PCIE2212
PCI Express™ SIGNAL SWITCH
SCDS209 – JUNE 2006
FEATURES
• Offers Bandwidth Allocation of PCI Express™ • Excellent Differential Skew (5 ps Max)
Signal Using Two-Lane 1:2
Multiplexer/Demultiplexer
• Vcc Operating Range From 1.7 V to 1.9 V
• Supports Data Rates of 2.5 Gbps
• Port-Port Crosstalk (–39 dB at 1.25 GHz)
• OFF Port Isolation (–38 dB at 1.25 GHz)
• Low ON-State Resistance (10 Ω Typ)
• Low Input/Output Capacitance (3.5 pF Typ)
DESCRIPTION/ORDERING INFORMATION
The TS2PCIE2212 can be used to muxltiplex/demultiplex two PCI Express™ lanes, each representing
differential pairs of receive (RX) and transmit (TX) signals. The switch operates at the PCI Express bandwidth
standard of 2.5-Gbps signal-processing speed. The device is composed of two banks, with each bank
accommodating two sources (source A and source B) and two destinations (destination A and destination B).
When a logic-level low is applied to the control (CTRL) pin, source A is connected to destination A and source B
is connected to destination B. When a logic-level high is applied to CTRL, source A is connected to destination
B, while source B and destination A are open.
• Minimal Propagation Delay
• ESD Performance Tested Per JESD 22
– 2000-V Human-Body Model
(A114-B, Class II)
– 1000-V Charged-Device Model (C101)

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltages are with respect to ground, unless otherwise specified.
(3) The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
(4) VIand VOare used to denote specific conditions for V
(5) IIand IOare used to denote specific conditions for I
(6) The package thermal impedance is calculated in accordance with JESD 51-7.
