LTC7227YV10

LTC7227 P-1 General Description The LTC7227 is 2 to 1 port analog switches. Their wide bandwidth and low bit-to-bit skew allow them to pass high-speed differential signals with good signal integrity. Each switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. Industry-leading advantages include a propagation delay of less than 250 ps, resulting from its low channel resistance and low I/O capacitance. Their high channel-to-channel crosstalk rejection results in minimal noise interference. Their bandwidth is wide enough to pass High-Speed USB 2.0 differential signals (480 Mbps). Features          RON is Typically 6Ω at VCC = 3.3 V Low Bit-to-Bit Skew: Typically 50 ps Low Crosstalk: -45 dB @ 250 MHz Low Current Consumption: 1.0 µA Near-Zero Propagation Delay: 250 ps Channel On-Capacitance: 3.5pF Typically VCC Operating Range: 1.65 V to 4.5 V >750 MHz Bandwidth (or Data Frequency) Available Packages: QFN1.8× 1.4-10L and MSOP-10L Applications   Differential Signal Data Routing USB 2.0 Signal Routing Order Information MODEL PACKAGE ORDERING NUMBER QFN1.8×1.4-10L LTC7227YFS10 MSOP-10L LTC7227YV10 LTC7222 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
