Diodes Incorporated PI6C2410LE

Overview

PI6C2410LE from Pericom Semiconductor is a low-skew, low-jitter PLL-based clock buffer with selectable divider/multiplier functionality, designed for PCI-X clock distribution in servers and workstations. It delivers four synchronous 3.3V CMOS outputs, supports 10–80 MHz input ranges via HF# control, features independent OE[3:0] output enable, and operates across –40°C to +85°C.

For engineers reviewing the PI6C2410LE datasheet, PI6C2410LE pinout, PI6C2410LE application, or PI6C2410LE equivalent, key selection criteria include input frequency range selection (HF#), per-output enable control, FBOUT feedback path configuration, and TSSOP-24 package compatibility with PCI-X timing compliance.

Technical Context

The PI6C2410LE integrates a PLL with dual-range input detection (10–40 MHz / 40–80 MHz) selected by HF#, enabling robust clock synthesis under spread-spectrum modulation for EMI reduction. Its internal feedback path (FBIN/FBOUT) ensures phase alignment between input and all outputs.

All four outputs (OUT0–OUT3) are fully synchronized with sub-200 ps skew and <200 ps cycle jitter at 66.67 MHz. Each output includes dedicated OE control, allowing dynamic power/EMI management without affecting other channels.

Key Specifications

Pinout & Package

PI6C2410LE is housed in a 24-pin Thin Shrink Small Outline Package (TSSOP-L), 173-mil wide, with 0.65 mm pitch, JEDEC MO-153F/AD compliant, Pb-free and Green (E suffix).

Manufacturer

Pericom Semiconductor (now part of Diodes Incorporated) is a fabless semiconductor company specializing in high-performance timing, interface, and signal-integrity solutions for computing and communications infrastructure.

The PI6C2410 product line was designed specifically for PCI-X clock distribution - delivering low skew, low jitter, and spread-spectrum compatibility to meet stringent server and workstation timing specifications.

FAQ

What is the function of the FBIN and FBOUT pins on PI6C2410LE?

FBIN accepts the feedback signal from FBOUT to close the PLL loop, ensuring phase alignment between CLKIN and all outputs. FBOUT is the buffered output of the internal PLL's feedback node, routed externally to FBIN. This configuration locks output phase to the input reference and minimizes accumulated jitter across the clock tree.

Can PI6C2410LE operate with a 5V supply?

No. PI6C2410LE is specified only for 3.3 V ±0.3 V operation. The absolute maximum supply rating is 4.6 V, and DC electrical characteristics (e.g., VOH/VOL, input thresholds) are characterized exclusively at 3.3 V. Using 5 V will exceed absolute maximum ratings and risk permanent damage.

How does HF# selection affect the PLL's lock range?

When HF# = LOW, the PLL locks to 10–40 MHz inputs; when HF# = HIGH, it locks to 40–80 MHz inputs. This dual-range architecture allows one device to support multiple clock sources without external component changes, and is essential for compatibility with both legacy and high-speed PCI-X configurations.

Is PI6C2410LE pin-compatible with PI6C2410Q (QSOP package)?

Yes - both PI6C2410LE (TSSOP-L) and PI6C2410Q (QSOP-Q) share identical pin numbering, signal mapping, and electrical behavior. The only difference is mechanical: L uses 0.65 mm pitch TSSOP; Q uses 0.635 mm pitch QSOP. Layouts require package-specific footprints but no schematic changes.
