NXP Semiconductors

PCA9527

3-channel bidirectional bus extender for HDMI, I

C-bus and SMBus

2. Features

n 3-channel, bidirectional buffer isolates capacitance allowing 1400 pF on port A and

400 pF on port B

n Exceeds 18 meters (above the maximum distance for HDMI DDC)

n Rise time accelerator and normal I/O on port A (no accelerator for CEC)

n Static level offset on port B

n Voltage level translation from 2.7 V to 5.5 V

n CEC is 5 V tolerant, powered by V

CC(B)

n Upgrade replacement over PCA9507 and PCA9517A for cable application

n I

C-bus, SMBus and DDC-bus compatible

n Active HIGH buffer enable input

n Open-drain input/outputs

n Lock-up free operation

n Supports arbitration and clock stretching across the repeater

n Accommodates Standard-mode and Fast-mode I

C-bus devices and multiple masters

n Powered-off high-impedance I

C-bus pins

n Port A operating supply voltage range of 2.7 V to 5.5 V

n Port B operating supply voltage range of 2.7 V to 3.6 V

n 5 V tolerant I

C-bus and enable pins

n 0 Hz to 400 kHz clock frequency (the maximum system operating frequency may be

less than 400 kHz because of the delays added by the repeater)

n ESD protection exceeds 8000 V HBM per JESD22-A114, 500 V MM per

JESD22-A115, and 1000 V CDM per JESD22-C101

n Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA

n Package offered: TSSOP10
