TS2PCIE2212

PCI Express™ SIGNAL SWITCH

SCDS209 – JUNE 2006

• Offers Bandwidth Allocation of PCI Express™ • Excellent Differential Skew (5 ps Max)

Signal Using Two-Lane 1:2

• Minimal Propagation Delay

Multiplexer/Demultiplexer

• ESD Performance Tested Per JESD 22

• Vcc Operating Range From 1.7 V to 1.9 V

– 2000-V Human-Body Model

• Supports Data Rates of 2.5 Gbps

(A114-B, Class II)

• Port-Port Crosstalk (–39 dB at 1.25 GHz)

– 1000-V Charged-Device Model (C101)

• OFF Port Isolation (–38 dB at 1.25 GHz)

• Low ON-State Resistance (10 Ω Typ)

• Low Input/Output Capacitance (3.5 pF Typ)

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.
