Product details
Overview
CY22150KFC from Cypress Semiconductor is a flash-programmable, single-PLL clock generator with six configurable CMOS clock outputs, 16-pin TSSOP package, 3.3V supply (2.5V output option), and two-wire serial programming interface. It accepts 8–30 MHz crystal or 1–133 MHz driven reference input and delivers up to 200 MHz output (3.3V) for timing-critical networking and telecom systems.
For engineers reviewing the CY22150KFC datasheet, CY22150KFC pinout, CY22150KFC application, or CY22150KFC equivalent, this page provides verified PLL architecture details, register-mapped post-divider options, VCO frequency constraints (100–400 MHz), crystal load capacitance programming (via register 13H), and industrial-grade temperature operation support.
Technical Context
The CY22150KFC implements a single integer-N PLL with programmable P (8–2055) and Q (2–129) counters, enabling precise VCO synthesis from reference inputs. Its dual divider banks (Bank 1/Bank 2) and crosspoint switch matrix allow independent routing of REF or VCO-derived signals to each of six outputs.
Each output supports seven configurations: /2 (two variants), /3, /4, /DIV1N, /DIV2N, or direct REF bypass. DIV1N and DIV2N are 7-bit programmable dividers (range 4–127), controlled via registers 0CH and 47H respectively, with dedicated source mux bits (DIV1SRC/DIV2SRC) selecting between REF or VCO feed.

Pinout & Package
16-pin TSSOP package with exposed thermal pad (not electrically connected); pin 1 marked by dot or bevelled corner; recommended solder profile per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XIN (1) | Reference Input | Accepts crystal (8–30 MHz) or external clock (1–133 MHz); internal programmable gain and load capacitance (register 12H/13H) enable vendor-agnostic crystal selection |
| VDD (2) | Digital Supply | 3.3V core supply; decoupling required within 5 mm of pin per layout guidelines |
| AVDD (3) | Analog Supply | 3.3V analog supply for PLL charge pump and oscillator; must be isolated from digital ground with ferrite bead or separate LDO |
| SDAT (4) | Serial Data I/O | Open-drain bidirectional data line for two-wire programming; requires 4.7 kΩ pull-up to VDD |
| AVSS (5) | Analog Ground | Return path for AVDD; must connect to solid analog ground plane, separated from digital ground at single point |
| VSSL (6) | LCLK Ground | Dedicated ground for low-skew LCLK outputs; routed separately to minimize crosstalk on high-speed clock traces |
| LCLK1–LCLK4 (7–8, 9, 12) | Configurable Outputs | Programmable voltage level (2.5V/3.3V via VDDL); each assigned to divider bank or REF bypass via crosspoint matrix (registers 44H–46H) |
| SCLK (10) | Serial Clock Input | Asynchronous clock for serial interface; max 1 MHz rate; synchronous edge-triggered sampling of SDAT |
| VDDL (11) | LCLK Output Supply | Selects 2.5V or 3.3V logic level for LCLK1–LCLK4; must match target receiver VDDIO requirements |
| VSS (13) | Digital Ground | Main digital return; connects to system GND plane; ties to AVSS and VSSL at single-point star ground |
| CLK5/CLK6 (14–15) | Fixed-Voltage Outputs | 3.3V-only outputs; no VDDL dependency; routed exclusively through Divider Bank 2 (register 47H controls DIV2N) |
| XOUT (16) | Crystal Output | Drives crystal in parallel-resonant mode; must be left floating if XIN is driven by external clock source |
Key Features
| Feature | Design Value |
|---|---|
| Flash-programmable PLL configuration | Nonvolatile storage retains custom P/Q/divider settings across power cycles; supports ≥100 reprogramming cycles for design iteration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar clock generator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si5338A-D-GM | Multi-PLL architecture (4 PLLs), higher integration (integrated LDOs, spread spectrum), 0.25 ps RMS jitter; requires I²C and external EEPROM for configuration. | Supports complex multi-domain systems (e.g., 5G fronthaul with >10 clock outputs); not drop-in due to different pinout and power sequencing. | Choose for ultra-low jitter and multi-PLL flexibility; avoid if cost-sensitive or constrained by PCB area for EEPROM. |
| ICS843002AGI-01LFT | Fixed-function 6-output LVDS clock generator; no PLL or programmability; 3.3V only; 100–250 MHz output range. | Used where clock tree is static and jitter <0.5 ps RMS is not required; lacks field reprogrammability and crystal load tuning. | Choose for simple, low-cost replacement when frequency plan is finalized and no future changes expected. |
Compared with Si5338A-D-GM and ICS843002AGI-01LFT, the CY22150KFC offers unique balance of flash programmability, crystal load compensation, and industrial temperature support in a compact TSSOP - ideal for mid-volume embedded systems requiring design agility without premium jitter performance.

FAQ
What is the default state of CY22150KFC after power-on?
At power-up, unprogrammed CY22150KFC defaults to all outputs three-stated, crystal oscillator active, and all registers set to zero. No clocks are generated until serial programming configures P/Q dividers and output enables (register 09H). Factory-shipped units are blank; distributor-programmed units boot with customer-defined JEDEC files loaded via CyClocksRT™.
Can CY22150KFC generate non-integer frequency ratios?
Yes - the CY22150KFC achieves fractional-equivalent outputs using integer-N PLL with programmable P and Q counters (Ptotal = 8–2055, Qtotal = 2–129) and post-dividers (/DIV1N or /DIV2N, range 4–127). While not a true fractional-N synthesizer, its 7-bit DIVxN resolution enables fine-grained steps (e.g., 125.0001 MHz) within VCO constraints (100–400 MHz).
How is crystal load capacitance programmed on CY22150KFC?
Crystal load capacitance is set via 8-bit register 13H (CapLoad), which controls on-die capacitors ranging from 6 pF to 30 pF in 0.09375 pF steps. The value is calculated as CapLoad = (CL – CBRD – 6 pF)/0.09375, where CL is crystal spec and CBRD is board parasitic capacitance (typically 2 pF). CyClocksRT automates this calculation from user-entered CL value.
Does CY22150KFC support spread-spectrum clocking (SSC)?
No - the CY22150KFC does not implement spread-spectrum modulation. Its PLL architecture is optimized for low-phase-noise, fixed-frequency synthesis. For EMI reduction, designers must rely on external filtering, careful PCB layout, or select alternative parts like the Si5338 series that integrate SSC capability.
