I C-bus/SPI to Quad Port Expander

Description

Features

e PI7C1401 is a SPI/I C Quad Port Expander, it’s speciﬁcal-

ly designed to manage common port types such as SFP+ and

QSFP+. e PI7C1401 provides an I C/SPI interface, an inter-

ꢀÎSupport Low-speed signals management and I C aggregation

across four ports

ꢀÎSupport multiple PI7C1401s to control high-port-count

through a single host interface

rupt output to host and four I C interfaces, general purpose pins

for low-speed control signals to the modules. e PI7C1401 can

be used a wide range of applications such as Networking, Tele-

com, Storage, Embedded. e typical usage for this device is

high volume applications requiring an “expander” to aggregate

ꢀÎSelectable I C(up to 1Mhz) or SPI(up to 33Mhz) host control

interface

ꢀÎAutomatic pre-fetching of critical, user-speciﬁed data from

the modules and stored into internal 32 Byte FIFO

all low-speed control and I C signals across four ports and pres-

ꢀÎAdvanced LED features for port status indication, including

ents a single I C or SPI interface to host. Multiple PI7C1401s can

programmable blinking and dimming

be used in high-port-count applications with one I C or SPI to

ꢀÎSupport standard SFF-8431, SFF-8472, SFF-8436, SFF-8679,

host. e system BOM cost can be cut by using smaller IO count

control devices(FPGAs, CPLDs, MCUs) and by reducing routing

layer congestion.

INF-8074 and other such low-speed electrical interfaces,

including a dedicated 100/400Khz I C interface to each port

ꢀÎCustomizable events which trigger an interrupt to the host

ꢀÎBroadcast Mode allows writes to all ports simultaneously

ꢀÎSeparate host-side I/O voltage: 1.8V to 3.3V
