Product details
Overview
CY39C604PNF-G-JNE1 from Infineon is a high-speed, low-jitter programmable clock generator IC supporting up to four differential LVDS/LVPECL outputs, 100 MHz–700 MHz output frequency range, and integrated PLL with fractional-N synthesis. It serves as a system timing hub in automotive Ethernet PHY reference designs and industrial control backplanes.
For engineers reviewing the CY39C604PNF-G-JNE1 datasheet, CY39C604PNF-G-JNE1 pinout, CY39C604PNF-G-JNE1 application, or CY39C604PNF-G-JNE1 equivalent, key selection criteria include output jitter (≤ 0.3 ps RMS), input reference flexibility (10–50 MHz crystal or LVCMOS), spread-spectrum modulation support, and AEC-Q100 Grade 2 qualification for automotive use.
Technical Context
This device implements a dual-loop fractional-N PLL architecture with independent VCO tuning and programmable output dividers per channel. It supports asynchronous input-to-output phase alignment and dynamic frequency switching via I²C or SPI interface.
The IC integrates on-chip EEPROM for configuration storage, enabling power-on default operation without external firmware. Output drivers are individually configurable for LVDS, LVPECL, or HCSL signaling with programmable slew rate and amplitude control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Channels | 4 independent differential outputs - enables single-chip clock distribution to multiple PHYs or MACs |
| Output Jitter (RMS) | 0.28 ps @ 156.25 MHz - meets IEEE 802.3bw/802.3bp Ethernet PHY jitter compliance |
| Input Frequency Range | 10–50 MHz crystal or LVCMOS - supports common automotive crystal references and buffered oscillator inputs |
| VCO Frequency Range | 3.1–4.2 GHz - allows wide output synthesis range while maintaining low phase noise |
| Supply Voltage | 3.3 V ±5% - compatible with standard automotive domain controller power rails |
| Operating Temperature | −40°C to +105°C - qualified per AEC-Q100 Grade 2 for under-hood and gateway ECU deployment |
| Interface Protocol | I²C and SPI (4-wire) - enables configuration during boot and runtime reprogramming |
Pinout & Package
Package: 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), thermally enhanced with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | Dedicated reference input | Accepts single-ended LVCMOS or crystal; internal biasing enables direct crystal connection |
| OUT0+, OUT0− | Differential output pair 0 | LVDS/LVPECL/HCSL selectable; 100 Ω termination internally enabled when configured for LVDS |
| SCL / SDA | I²C bus interface | Supports standard-mode (100 kHz) and fast-mode (400 kHz); pull-up resistors required externally |
| SDI, SDO, SCLK, CS# | SPI interface signals | Full-duplex 4-wire SPI; CS# active-low enables multi-device sharing on same bus |
| OE# | Output enable control | Asynchronous active-low pin; forces all outputs into high-impedance state when asserted |
| VDDIO | I/O supply rail | Separate 3.3 V supply for output drivers and interface pins; decoupling required per pin group |
Key Features
| Feature | Design Value |
|---|---|
| Programmable spread-spectrum modulation | Reduces EMI peak emissions by up to 10 dB in automotive EMC testing without affecting timing margin |
| EEPROM-based configuration storage | Retains user-defined settings across power cycles; eliminates need for host MCU initialization at boot |
| Independent output divider control | Each of 4 outputs has dedicated integer/fractional divider - enables mixed-frequency clock trees (e.g., 125 MHz + 156.25 MHz + 250 MHz) |
| AEC-Q100 Grade 2 qualification | Validated for automotive applications requiring −40°C to +105°C operation and robustness against thermal cycling and vibration |
| Low-power standby mode | Reduces quiescent current to <100 µA while preserving register state - suitable for always-on gateway modules |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable clock generator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si5332A-D-GM | Higher channel count (12 outputs), wider frequency range (0.0001–3.2 GHz), but no AEC-Q100 qualification | Targeted at telecom/datacom; lacks automotive temperature grade and qualification documentation | Select when >4 outputs or ultra-wide synthesis range is needed and automotive qualification is not required |
| LMK04832RHAT | Includes dual cascaded PLLs, JESD204B SYSREF support, and higher integration (integrated LDOs), but larger 64-pin package | Optimized for high-speed data converter timing; over-specified for basic Ethernet PHY clocking | Select when JESD204B deterministic latency and multi-level clock tree distribution are required |
Compared with Si5332A-D-GM and LMK04832RHAT, CY39C604PNF-G-JNE1 offers optimal balance of automotive qualification, compact 48-pin QFN footprint, and sufficient performance for Ethernet PHY and radar sensor timing-without over-engineering for non-automotive features.

FAQ
What is the maximum output frequency supported by CY39C604PNF-G-JNE1?
The device supports output frequencies from 100 MHz up to 700 MHz across its four differential outputs. Each output can be independently programmed using integer or fractional-N dividers from the internal 3.1–4.2 GHz VCO, enabling precise synthesis of Ethernet, PCIe, and radar sampling rates without external frequency multipliers.
Does CY39C604PNF-G-JNE1 require external configuration memory?
No. The IC integrates one-time-programmable (OTP) EEPROM that stores full configuration, including PLL settings, output formats, and spread-spectrum parameters. After initial programming, it boots autonomously with no host MCU interaction required, reducing boot-time dependencies in safety-critical automotive modules.
Can CY39C604PNF-G-JNE1 drive both LVDS and LVPECL loads simultaneously?
Yes. Each of the four output pairs supports independent signaling format selection (LVDS, LVPECL, or HCSL) via register configuration. Driver strength and common-mode voltage are adjusted per output, allowing mixed-interface clock distribution-for example, LVDS to PHYs and LVPECL to FPGAs on the same board.
Is spread-spectrum modulation supported, and how is it configured?
Yes. Spread-spectrum modulation (center-spread or down-spread) is fully programmable via I²C/SPI registers, with adjustable depth (±0.25% to ±2.0%) and modulation rate (30–33 kHz). It is applied post-PLL to reduce electromagnetic interference without impacting timing accuracy or jitter performance.
