Infineon Technologies CY22800FXC-005A

Overview

CY22800FXC-005A from Cypress Semiconductor is a field-programmable universal clock generator with integrated PLL, supporting X6 multiplication mode for consumer electronics timing. It accepts 8–30 MHz crystal or 0.5–33.33 MHz CLKIN input and delivers CLKA output at 3–200 MHz and CLKB as reference output (REFOUT), operating at 3.3 V in an 8-pin SOIC package for HDTV, STB, and DVD recorder applications.

For engineers reviewing the CY22800FXC-005A datasheet, CY22800FXC-005A pinout, CY22800FXC-005A application, or CY22800FXC-005A equivalent, this device offers programmable frequency synthesis without external crystals, low-jitter clock generation, spread-spectrum EMI reduction capability, and reprogrammability up to 100 times - critical for rapid prototyping and BOM consolidation in audio/video system design.

Technical Context

The CY22800FXC-005A implements Cypress's proprietary PLL architecture optimized for X6 multiplication, accepting reference inputs from either crystal (8–30 MHz) or external clock (0.5–33.33 MHz) and generating high-accuracy CLKA outputs from 3 to 200 MHz. Its internal divider chain supports REFOUT on CLKB without modulation.

No spread spectrum or VCXO functionality is enabled in the -005A configuration per Table 2; it operates exclusively in fixed-ratio X6 multiplier mode with no analog tuning voltage required. All three outputs (CLKA, CLKB, CLKC) are functional but CLKB is designated as REFOUT and CLKC is tied to VSS in this variant.

Supply support for CY22800FXC-005A includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

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

The CY22800 product line was designed specifically for flexible, low-cost clock synthesis in consumer electronics - enabling BOM reduction, EMI mitigation, and rapid timing validation without custom ASIC development.

FAQ

Is CY22800FXC-005A pin-compatible with other CY22800 variants?

Yes - all CY22800 devices share identical 8-pin SOIC pinout and power sequencing. However, pin functions (e.g., FS0/VCXO, CLKC/VSS) are configuration-dependent; the -005A variant ties CLKC to VSS and configures CLKB exclusively as REFOUT, so board-level reuse requires verification of signal routing against the target configuration's pin definition table.

Does CY22800FXC-005A support spread spectrum clocking (SSC)?

No - the -005A configuration explicitly disables spread spectrum and VCXO features per Table 2 in the datasheet. It operates solely in fixed-ratio X6 multiplication mode with no modulation control or analog tuning voltage capability. SSC-enabled variants include codes -015A through -022A and -115A through -122A.

What programming hardware is required to configure CY22800FXC-005A?

The CY36800 programmer dongle is required, along with Cypress-provided configuration software and the specific .cfg file for code -005A. The device is programmed via the XIN/XOUT pins using a 2-wire serial interface; no JTAG or external microcontroller is needed, and programming can occur in-system or during board test.

Can CY22800FXC-005A generate three independent clock outputs?

No - in the -005A configuration, CLKC is internally connected to VSS and disabled per Table 1 footnote and Figure 1 pin mapping. Only CLKA (X6-multiplied output) and CLKB (REFOUT) are active; CLKC is not available as a functional clock output in this variant.
