Product details
Overview
CY22150FZXIT from Infineon Technologies (formerly Cypress) is a single-PLL, flash- and I²C-programmable clock generator delivering six configurable outputs up to 200 MHz, supporting both crystal (8–30 MHz) and driven reference inputs (1–133 MHz), with 3.3 V operation and optional 2.5 V LCLK outputs, widely deployed in industrial networking and telecom timing subsystems.
For engineers reviewing the CY22150FZXIT datasheet, CY22150FZXIT pinout, CY22150FZXIT application, or CY22150FZXIT equivalent, key selection criteria include its field-programmable PLL architecture, nonvolatile flash reprogrammability (up to 100 cycles), I²C volatile configuration (address 0x69), industrial temperature range (–40°C to +85°C), and TSSOP-16 package compatibility with legacy clock designs.
Technical Context
The CY22150FZXIT implements a single integer-N PLL with programmable P and Q dividers (Qtotal = Q + 2, range 2–129) and dual post-divider banks (DIV1N/DIV2N, 7-bit resolution), enabling precise frequency synthesis from a single reference source. Its crosspoint switch matrix routes either the VCO output ((REF × P)/Q) or the raw REF directly to any of six outputs.
It supports two independent reference modes: crystal oscillator with programmable gain (XDRV bits) and load capacitance (CapLoad register 13H, 8-bit, 0.09375 pF step), or external clock input with four drive strength settings. All six outputs are individually configurable for voltage level (VDDL-referenced LCLK1–LCLK4 or fixed 3.3 V CLK5/CLK6) and source path (PLL, REF bypass, or divider bank).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Outputs | 6 independent, configurable clock outputs (LCLK1–LCLK4 at VDDL; CLK5/CLK6 at 3.3 V) |
| Input Frequency Range | 8–30 MHz crystal or 1–133 MHz driven reference - enables flexible sourcing across cost/performance tiers |
| Output Frequency Range | 80 kHz–200 MHz (3.3 V), 80 kHz–166.6 MHz (2.5 V) - covers PCIe, Ethernet, and processor clocking needs |
| PLL Architecture | Integer-N with P/Q dividers and dual post-divider banks (DIV1N/DIV2N) - supports multi-ratio synthesis without external components |
| Programming Interface | I²C slave address 0x69 (volatile) + on-chip flash (nonvolatile, 100-cycle endurance) - enables both runtime tuning and factory programming |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded systems and base station timing modules |
| Supply Voltages | VDD = 3.3 V ±10%; VDDL = 2.5 V or 3.3 V; AVDD/AVSS for analog PLL section - separates digital and analog domains to minimize jitter |
Pinout & Package
Package: 16-pin TSSOP (4.4 mm × 5.0 mm, 0.65 mm pitch), RoHS-compliant, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XIN | Reference Input | Accepts crystal (8–30 MHz) or external clock (1–133 MHz); internal programmable gain and load capacitance enable broad crystal vendor compatibility |
| VDD / AVDD / VDDL | Power Supplies | VDD (digital core), AVDD (analog PLL), VDDL (LCLK output driver rail) - independent rails reduce supply noise coupling into clock paths |
| SDA / SCL | I²C Interface | Two-wire serial interface (address 0x69) for volatile in-system configuration; supports dynamic frequency updates during operation |
| LCLK1–LCLK4 | Configurable Outputs | Four outputs referenced to VDDL (2.5 V or 3.3 V); each selectable via crosspoint matrix to PLL, REF, or divider bank outputs |
| CLK5 / CLK6 | Fixed-Voltage Outputs | Dedicated 3.3 V outputs with no VDDL dependency - simplify power sequencing in mixed-voltage systems |
| VSS / AVSS / VSSL | GND Planes | Separate digital ground (VSS), analog ground (AVSS), and LCLK ground (VSSL) - critical for low-jitter performance and EMI control |
Key Features
| Feature | Design Value |
|---|---|
| Flash-based nonvolatile programming | Enables one-time factory configuration or field reprogramming up to 100 times - eliminates custom part SKUs and supports design iteration without hardware change |
| Programmable crystal oscillator gain & load capacitance | Two-bit XDRV control and 8-bit CapLoad register (register 13H) allow precise matching to crystal ESR and CL - removes need for external load caps and improves startup reliability |
| Independent output voltage referencing | LCLK1–LCLK4 driven from VDDL (2.5 V or 3.3 V), while CLK5/CLK6 are fixed at 3.3 V - supports mixed-signal SoC interfaces with varying I/O voltage requirements |
| Crosspoint switch matrix | Each of six outputs can be routed to PLL output, direct REF, or either post-divider bank - enables asymmetric clock trees (e.g., CPU @ 100 MHz, DDR @ 200 MHz, PCIe @ 125 MHz) from one device |
Applications
| Industrial PLC Timing | Telecom Line Card Clocking |

Equivalent & Alternatives
Two verified alternatives exist for CY22150FZXIT, differing in architecture, programmability, and temperature grade.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si5338A-D-GM (Silicon Labs) | Multi-output, multi-PLL synthesizer with fractional-N capability; supports <1 ps RMS jitter; requires external EEPROM for nonvolatile config | Higher precision required in RF sampling or high-speed ADC clocking; not drop-in due to different pinout and I²C register map | Select when ultra-low jitter (<0.3 ps) and fractional synthesis are mandatory; accept added complexity and cost |
| ICS8430I-01T (Renesas) | Fixed-function, non-programmable 6-output LVDS clock fanout buffer; no PLL or frequency synthesis; operates at –40°C to +85°C | Used only for clock distribution (not generation); requires external oscillator; lower power and cost but zero frequency flexibility | Select only if system already provides all required frequencies and only fanout/buffering is needed - no replacement for synthesis capability |
Compared with Si5338A-D-GM and ICS8430I-01T, CY22150FZXIT uniquely balances field-programmable synthesis, industrial temperature operation, and TSSOP-16 footprint - making it optimal for cost-sensitive, space-constrained industrial designs needing moderate jitter and full frequency customization without external memory.

FAQ
What is the default state of CY22150FZXIT after power-up?
Upon power-up, an unprogrammed CY22150FZXIT enters a default state where all outputs are three-stated, the crystal oscillator circuit is active, and internal registers retain factory-reset values. If previously programmed via flash, it boots with those settings; if configured via I²C only, it reverts to the last flash state unless reinitialized by host firmware.
Can CY22150FZXIT generate non-integer multiples of the reference frequency?
No - the CY22150FZXIT uses an integer-N PLL architecture only. Output frequencies are strictly integer ratios of the reference (REF × P/Q, then divided by post-dividers). Fractional-N synthesis is not supported; for non-integer ratios, external clock sources or alternative synthesizers like Si5338 are required.
How is crystal load capacitance configured on CY22150FZXIT?
Crystal load capacitance is set via 8-bit register 13H (CapLoad), with resolution of 0.09375 pF per LSB. The value is calculated using CapLoad = (CL – CBRD – 6 pF) / 0.09375, where CL is the crystal's specified load capacitance and CBRD is board parasitic capacitance (typically ~2 pF). This register is programmed during initialization via I²C or flash.
Does CY22150FZXIT support spread-spectrum clocking (SSC)?
No - the CY22150FZXIT does not implement spread-spectrum clocking. Its PLL is optimized for low-jitter, fixed-frequency synthesis. For EMI reduction via SSC, designers must use external modulation circuitry or select alternative clock generators such as Infineon's XMC-based timing solutions or Silicon Labs' Si534x family.
