PI2EQX3201BZFEX

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX3201BZFEX is a low-power signal re-driver manufactured by Diodes Incorporated. It features two pairs of 3.2Gbps differential signal channels with 100Ω differential CML I/Os. The device operates within a VCC range of 1.5V to 1.8V and consumes approximately 100mW per channel in active mode. It includes an integrated spread-spectrum capable clock buffer output. Configuration is managed via four select bits (SEL) for adjustable transmitter de-emphasis, amplitude, and receiver equalization. Each channel supports input signal level detection and squelch functions. The component is housed in a 36-pad TQFN package.

Signal Buffers, Repeaters, Splitters FAQ

How is the standby mode activated?

Standby mode is activated by driving the EN_X Bus Enable pins to a Low Voltage CMOS (LVCMOS) low state, which selects a low power down state.

What determines the output driver state when the input signal is weak?

If the input signal level falls below the active threshold level (Vth-), the output driver switches off, and the pin is pulled to VDD via a high impedance resistor. If it falls below the signal detect threshold, outputs are driven to the common mode voltage.

What is the function of the SEL pins?

The SEL pins (SEL_A and SEL_B) are used to configure the amplifier, equalizer, and de-emphasis settings. They utilize internal 50KΩ pull-up resistors and allow for programmable adjustment to optimize signal integrity.
