Diodes Incorporated PI6C10804WE

Overview

PI6C10804WE from Pericom Semiconductor is a 1.5V–2.5V, 180 MHz, 1:4 non-inverting clock buffer optimized for low-skew, low-jitter networking clock distribution. It delivers output-to-output skew as low as 70 ps (at 2.5V), propagation delay ≤3.0 ns, and supports 3.3V-tolerant input clocks. It serves as a synchronous timing distribution node in Ethernet switch PHY interfaces and packet processing subsystems.

For engineers reviewing the PI6C10804WE datasheet, PI6C10804WE pinout, PI6C10804WE application, or PI6C10804WE equivalent, this page provides verified electrical specs, package mapping to 8-pin SOIC (W), real-world skew performance across voltage rails, and validated alternatives for clock tree design in telecom and enterprise infrastructure.

Technical Context

The PI6C10804WE implements a single-input, quad-output CMOS buffer with OE-controlled output enable functionality. Its internal architecture maintains tight matching between output paths to achieve sub-100 ps output-to-output skew under 2.5V operation and full temperature range (–40°C to +85°C).

It operates across three supply rails-1.5V, 1.8V, and 2.5V-with corresponding AC performance trade-offs: max frequency scales from 200 MHz (1.5V) to 250 MHz (2.5V), while output skew degrades from 100 ps to 70 ps and propagation delay tightens from 3.0 ns to 2.0 ns.

Manufacturer

Pericom Semiconductor was a fabless provider of high-performance timing, interface, and signal integrity solutions, acquired by Diodes Incorporated in 2016; its clock products remain widely deployed in networking and communications infrastructure.

The PI6C10804WE belongs to Pericom's PI6C family of low-skew clock buffers, engineered specifically for synchronous data plane clocking in carrier-grade switches, routers, and optical line cards where deterministic skew and jitter performance are non-negotiable.

FAQ

What is the maximum operating temperature for the PI6C10804WE?

The PI6C10804WE is rated for continuous operation from –40°C to +85°C ambient temperature. Its AC characteristics-including skew, propagation delay, and duty cycle-are fully specified across this range, with worst-case skew measured at maximum temperature. The device also supports storage up to +150°C, confirming robustness for reflow and long-term deployment in thermally demanding chassis environments.

Does the PI6C10804WE require external termination resistors?

No, the PI6C10804WE uses CMOS output drivers and does not require external termination resistors. Its outputs are designed to drive standard 5pF capacitive loads directly, and the datasheet specifies rise/fall times and skew under 5pF loading conditions. For heavier loads (>10pF) or longer traces, controlled impedance routing and local decoupling are recommended-but no series or parallel termination is needed.

Can the OE pin be left unconnected or tied permanently high?

The OE pin must not be left floating; it has an internal pull-down but is not latch-up protected against noise. For permanent enable, tie OE directly to VDD. For dynamic control, drive it with a clean logic signal referenced to the same VDD rail. Leaving OE unconnected risks intermittent output disable due to noise coupling, especially in high-density PCB layouts near switching regulators or RF sections.

Is there a pin-compatible upgrade path for the PI6C10804WE?

No direct pin-compatible upgrade exists within Pericom's portfolio. The PI6C10804WE's 8-pin SOIC (W) footprint and 1:4 topology are unique to this generation. Later Diodes-incorporated equivalents like the PI6C20400LEX use the same package but differ in pinout (e.g., OE relocated) and lack 1.5V support. Migration requires schematic and layout revision-not drop-in replacement.
