PI2EQX3201BZFE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX3201BZFE is a low-power signal re-driver manufactured by Diodes Incorporated. It features two pairs of 3.2Gbps differential signal channels with adjustable transmitter de-emphasis and amplitude, alongside adjustable receiver equalization. The device includes one spread spectrum capable clock buffer output and utilizes 100Ω differential CML I/Os. It operates within a VCC range of 1.5V to 1.8V and consumes approximately 100mW per channel. The component is housed in a 36-pad TQFN (ZF36) package.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix ZFE confirms the Pb-free and Green packaging configuration as documented. Confirm that the 36-pad TQFN package dimensions align with your PCB footprint requirements. Ensure voltage supply rails strictly remain within the 1.5V to 1.8V operating range to maintain specified electrical characteristics.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring 3.2Gbps serial data re-driving with flexible equalization settings. Consider the 36-pin TQFN form factor for space-constrained layouts. Evaluate the need for built-in clock buffering and spread spectrum support if jitter reduction is critical for the target application environment.

Signal Buffers, Repeaters, Splitters FAQ

How does the device handle low-level input signals?

Each channel features an input signal level detect and output squelch function. If the input level falls below the active threshold, the output driver switches off and pulls to VDD via a high impedance resistor.

What is the purpose of the SEL pins?

The SEL pins allow users to program the equalizer, amplifier, and de-emphasis settings using four select bits to optimize performance for different physical mediums.

Does the device support power saving modes?

Yes, it includes a Stand-by Mode operated by a Bus Enable pin, which selects a low power down state when LVCMOS low is applied.
