PI3L500
3.3V, 8-Channel, 2:1 Mux/DeMux
Gigabit Ethernet LAN Switch with Single Enable
Features
Description
• RON is 4Ω typical
• Low bit-to-bit skew: 200ps
• Low Crosstalk: –22dB @ 250MHz
Pericom Semiconductor’s PI3Lseries of switch circuits are produced
using the Company’s advanced sub-micron CMOS technology,
achieving industry leading performance.
• Near-Zero propagation delay: 250ps
• Switching speed: 9ns
• Channel On capacitance: 10pF (typical)
• Live Insertion Capable
• Status Indicator LEDs Switched with Ethernet pairs
• VCC Operating Range: +3.0V to +3.6V
• ESD>3000V . . . Human Body Model
• >350 MHz bandwidth (or data frequency)
The PI3L500 is a 16- to 8- Channel multiplexer/demultiplexer LAN
Switch with Hi-Z outputs. Industry leading advantages include a
propagation delay of less than 250ps, resulting from its low channel
resistance and I/O capacitance. The device multiplexes differential
outputs from a Gigabit Ethernet transceiver (PHY) device to one
of two corresponding B1 or B2 outputs. The switch is bidirectional
and offers little or no attenuation of the high-speed signals at the
outputs. It is designed for low bit-to-bit skew, high channel-to-
channel noise isolation and is compatible with various standards,
• Packaging:
such as 10/100/1000 Base-T (Ethernet).
· Pb-free and Green 56-contact TQFN (ZF)
Generally, this part can be used to replace mechanical relays in
· 56-contact TQFN (ZF)
low-voltage LAN applications that interface a physical layer over
CAT 5 or CAT 6 unshielded twisted pair cable through an isolation
transformer.

Notes:
1. CL = Load capacitance: includes jig and probe capacitance.
2. RT = Termination resistance: should be equal to ZOUT of the Pulse Generator
3. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
4. All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, ZO = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns.
et4U.com5. The outputs are measured one at a time with one transition per measurement.
