Diodes Incorporated PI6CXG06F62AFBEIE

Overview

PI6CXG06F62AFBEIE from Diodes Incorporated is an ultra-low-jitter 6-output FlexOut clock generator with user-configurable differential signaling per bank (LVPECL/LVDS/HCSL), 156.25 MHz output frequency, <0.1 ps RMS phase jitter (12 kHz–20 MHz), and industrial temperature range (−40°C to +85°C). It integrates a high-performance PLL-based embedded clock source and supports dual-bank independent output voltage control (2.5 V/3.3 V) for mixed-interface systems such as Ethernet switches and PCIe-based telecom backplanes.

For engineers reviewing the PI6CXG06F62AFBEIE datasheet, PI6CXG06F62AFBEIE pinout, PI6CXG06F62AFBEIE application, or PI6CXG06F62AFBEIE equivalent, key selection criteria include per-bank signaling configurability, sub-40 ps intra-bank skew, HCSL-compatible IREF tuning, LVPECL/LVDS/HCSL termination guidance, and LQFP-48 (FBE) thermal pad layout compatibility.

Technical Context

The device implements a PLL-based clock synthesis architecture with integrated VCO and programmable divider, delivering 156.25 MHz at all six differential outputs. Each of the two banks (A and B) features independent OPMODE[1:0] control pins enabling real-time selection among LVPECL, LVDS, or HCSL signaling standards without reconfiguration of power supplies.

Core timing integrity is maintained via separate VDD_INTCLK (for internal oscillator), VDD (core logic), VDDO (output buffers), and VEE (LVPECL negative rail) supplies - allowing precise noise isolation between clock generation and output stages. The IREF pin provides external 475 Ω resistor-based current reference for HCSL output common-mode voltage calibration.

Key Specifications

Pinout & Package

PI6CXG06F62AFBEIE is housed in a 48-pin Low-Profile Quad Flat Package (LQFP) with exposed ground pad (FBE code), RoHS-compliant and halogen-free ("Green"). The package supports standard reflow profiles and provides thermal relief via the GND-connected EPAD (Pin 49).

FAQ

What output signaling standards does PI6CXG06F62AFBEIE support, and how are they selected?

The device supports LVPECL, LVDS, and HCSL per output bank (A and B), selected via hardwired OPMODEA[1:0] and OPMODEB[1:0] pins. LVPECL requires VEE = 0 V and VDDO = 3.3 V; LVDS uses VDDO = 2.5 V or 3.3 V with internal 100 Ω termination; HCSL needs IREF tied to 475 Ω to GND and VDDO = 3.3 V. No software or I²C interface is required - configuration is purely pin-driven.

How is phase jitter performance verified, and what test conditions apply?

Phase jitter is measured as RMS value over 12 kHz–20 MHz offset bandwidth per JEDEC Standard JESD65B, using a calibrated phase noise analyzer. The specified <0.1 ps maximum applies to LVPECL outputs at 156.25 MHz with VDD = 3.3 V, TA = 25°C, and matched 50 Ω terminations. Measured values are typ. 0.07 ps under these conditions, confirmed in DS43533 Rev 2-2 Section 5.

Can PI6CXG06F62AFBEIE drive both LVPECL and HCSL loads simultaneously, and what design considerations apply?

Yes - Bank A can be configured as LVPECL (OPMODEA = 00) while Bank B is set to HCSL (OPMODEB = 10), using separate VDDO supplies. Critical considerations include routing VEE only to LVPECL bank traces, connecting IREF exclusively to Bank B's 475 Ω resistor, and avoiding shared VDDO nets between banks to prevent cross-talk-induced jitter degradation.

What thermal management practices are recommended for reliable operation at 85°C ambient?

Mount the LQFP-48 package on a 4-layer PCB with ≥2 oz copper on inner layers and direct thermal vias under the exposed pad (Pin 49) to internal ground planes. Use ≥10 thermal vias (0.3 mm diameter) and ensure ≥70% solder coverage on the EPAD. With total power dissipation ≤210 mA × 3.3 V ≈ 693 mW, junction temperature remains below 115°C at 85°C ambient when following Diodes' layout guidelines in DS43533 Section 13.
