Infineon Technologies CY22800FXC-029A

Overview

CY22800FXC-029A from Cypress Semiconductor is a field-programmable, 3.3V universal clock generator optimized for HDTV and set-top box systems requiring USB, Ethernet, and iLink timing. It accepts a 27 MHz crystal or external clock input and delivers four precisely configured outputs: CLKA at 24.576 MHz (USB audio), 25 MHz (Ethernet PHY), 20 MHz, and 48 MHz (iLink); CLKB fixed at 27 MHz. Its integrated PLL supports low-jitter synthesis with no spread spectrum or VCXO functionality enabled per configuration.

For engineers reviewing the CY22800FXC-029A datasheet, CY22800FXC-029A pinout, CY22800FXC-029A application, or CY22800FXC-029A equivalent, this device serves as a reprogrammable, single-chip timing solution for multi-standard consumer electronics where deterministic frequency accuracy, EMI control via optional SSCG, and pin-compatible configuration flexibility are critical selection criteria.

Technical Context

The CY22800FXC-029A implements Cypress's proprietary integer-N PLL architecture with programmable output dividers and three independent clock outputs (CLKA, CLKB, CLKC) plus reference output (XOUT). Input handling supports dual-mode reference sources: crystal (8–30 MHz) or external clock (0.5–100 MHz), with internal oscillator buffering and phase alignment logic.

Configuration is stored in on-chip nonvolatile memory and supports up to 100 reprogramming cycles via the CY36800 dongle. Pin functions are context-dependent-FS0/VCXO, CLKB/FS1, CLKA/FS0, and CLKC/FS2/VSS serve dual roles based on selected configuration mode, enabling flexible frequency select and functional remapping without hardware change.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) is a fabless semiconductor company specializing in programmable system-on-chip solutions, memory, and timing devices for consumer, industrial, and automotive markets.

The CY22800 product line was designed to replace multiple fixed-frequency crystals and oscillators in digital AV systems - delivering field-configurable, low-jitter clock synthesis in minimal footprint for HDTV, STB, and multimedia endpoint applications.

FAQ

What programming tool is required to configure CY22800FXC-029A?

The CY22800FXC-029A is programmed using the Cypress CY36800 dongle programmer with the associated ClockWizard software. This tool loads precompiled configuration files (e.g., "CY22800-029A.hex") that define input/output frequencies, FS pin mapping, and output enable states. No custom firmware development is needed - configuration is performed via GUI-driven bitstream generation and serial programming.

Does CY22800FXC-029A support spread spectrum clocking (SSCG)?

No. The CY22800FXC-029A configuration explicitly disables spread spectrum functionality (SS = N in Table 2), as confirmed by its "HDTV, STB clock generator (USB/Ethernet/iLink clock)" designation. It delivers fixed-frequency, low-jitter outputs without modulation - ideal for applications where deterministic timing and minimal spectral spreading are required, such as USB 2.0 and IEEE 1394a.

Can CLKB be reconfigured to a different frequency in CY22800FXC-029A?

No. In the CY22800FXC-029A configuration, CLKB is hardwired to output 27 MHz - matching the XIN reference frequency - and cannot be modified via FS pins or programming. This fixed relationship is defined in the factory-programmed configuration file and remains invariant across all 100 reprogramming cycles.

Is the 8-pin SOIC package of CY22800FXC-029A RoHS-compliant and lead-free?

Yes. The CY22800FXC-029A uses a lead-free, RoHS-compliant 8-pin SOIC package (package code "FXC") with matte tin plating. Cypress documentation (001-07704 Rev. *B, page 1) confirms full compliance with EU Directive 2011/65/EU and JEDEC J-STD-609A Class 3 marking. No exemptions apply.
