Product details
Overview
CY22393FC from Cypress Semiconductor is a three-PLL, serial- and flash-programmable clock generator in 16-pin TSSOP, delivering up to six CMOS clock outputs (CLKA–CLKC, CLKD, CLKE) with frequency range 1 MHz–166 MHz, ultra-wide divide counters (11-bit P, 8-bit Q), and configurable crystal load capacitance (6–30 pF). It supports commercial temperature operation and is used in FPGA-based communication interface timing, embedded processor reference clocking, and multi-clock domain industrial controllers.
For engineers reviewing the CY22393FC datasheet, CY22393FC pinout, CY22393FC application, or CY22393FC equivalent, key selection criteria include its triple-PLL architecture, field-programmable flash memory, 3.3 V operation, glitch-free S2-controlled frequency switching, and CyClocksRT™ software configurability - all critical for deterministic multi-frequency synthesis in space-constrained designs.
Technical Context
The CY22393FC integrates three independent PLLs, each with programmable 11-bit feedback divider (P) and 8-bit reference divider (Q), enabling precise integer-N synthesis from a single 8–30 MHz crystal or external reference. Its 4×4 crosspoint switch routes PLL outputs to six configurable clock pins with per-output 7-bit post-dividers.
It features digital VCXO capability via on-die crystal load capacitor tuning (6–30 pF in 0.375 pF steps), two-wire serial interface (SDAT/SCLK) for in-system configuration, and power management modes including shutdown, suspend, and output enable - all implemented without external components.

Pinout & Package
Package: 16-pin TSSOP (4.4 mm × 5.0 mm, 0.65 mm pitch), RoHS-compliant, NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XTALIN (Pin 4) | Reference oscillator input | Accepts parallel-resonant fundamental-mode crystal (8–30 MHz) or driven clock (1–166 MHz); bypasses internal load caps when driven |
| XTALOUT (Pin 5) | Crystal feedback output | Drives crystal's other terminal; left floating when using external clock source |
| CLKA–CLKC (Pins 10, 9, 1) | Configurable CMOS clock outputs | Each routed from PLL1/2/3 via crosspoint switch and 7-bit post-divider; support independent frequency assignment |
| CLKD / CLKE (Pins 7, 8) | Additional CMOS clock outputs | CLKD sourced from PLL2 or PLL3; CLKE sourced from PLL1 with /2, /3, or /4 synchronous post-divider |
| SDAT (Pin 12) / SCLK (Pin 13) | Two-wire serial interface | SDAT latches S0 at startup; SCLK latches S1; both enable register access and dynamic VCXO tuning |
| S2/SUSPEND (Pin 15) | Frequency select / suspend control | Selects between two preloaded PLL1 or output divider configurations; glitch-free switching across eight frequency combinations |
| SHUTDOWN/OE (Pin 16) | Global output control | Active-low: places all outputs in high-impedance state and powers down PLLs (shutdown mode) or only tristates outputs (OE mode) |

Equivalent & Alternatives
CY22393FC has documented alternatives within Cypress's clock generator portfolio for design flexibility and lifecycle continuity.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY223931FC | NiPdAu lead finish (vs. standard SnPb); identical electrical specs and pinout | Required for lead-free assembly and RoHS-compliant medical/industrial products | Select when Pb-free compliance is mandated; no redesign needed |
| CY22394FC | Adds 100–400 MHz LVPECL output (P+/P–); replaces one CMOS output with PECL driver | Needed for high-speed SerDes clocking (e.g., PCIe Gen2, SATA) where CMOS swing is insufficient | Choose only if >200 MHz differential clocking is required; adds external termination complexity |
Compared with CY223931FC, CY22393FC offers lower-cost SnPb assembly but lacks RoHS compliance; compared with CY22394FC, it provides maximum CMOS output count at the expense of high-frequency differential capability - making it optimal for cost-sensitive, multi-rail CMOS systems.

FAQ
What is the maximum output frequency supported by CY22393FC?
The CY22393FC supports up to 200 MHz CMOS output frequency in commercial-grade operation. This is achieved using PLL1 with optimized P/Q values and direct routing through the crosspoint switch to CLKA or CLKC, as confirmed in the "Selection Guide" table on page 2 of datasheet 38-07186 Rev. *N. Output frequencies above 166 MHz require careful layout and load capacitance control to maintain signal integrity.
Does CY22393FC support spread-spectrum clocking (SSC)?
No, CY22393FC does not implement spread-spectrum clocking. Its PLL architecture is fixed integer-N with no dithering or modulation capability. The device achieves low jitter (<150 ps RMS) through linear on-die load capacitors, optimized loop filters, and clean power domain separation - not spectral spreading. SSC must be implemented externally or with alternate parts like CY27410.
Can CY22393FC operate with a 1.8 V input clock?
No. CY22393FC requires a 3.3 V supply and accepts only LVTTL-compatible inputs (≥2.0 V high threshold). A 1.8 V clock signal is below the VIH(min) specification of 2.0 V and will not reliably register. Level-shifting to 3.3 V LVTTL or using a compatible 3.3 V oscillator is mandatory, as stated in the "Operating Conditions" section (page 15) of datasheet 38-07186.
Is CyClocksRT™ software required to configure CY22393FC?
CyClocksRT™ is strongly recommended but not strictly required. Configuration can be performed via two-wire serial interface using custom firmware that implements the protocol defined in Section 11 ("Serial Programming Interface Timing") of datasheet 38-07186. However, CyClocksRT™ provides validated GUI-based register mapping, VCXO tuning, jitter analysis, and flash programming - reducing bring-up time by >70% versus manual register writes.
