Infineon Technologies CY22800FXC-032A

Overview

CY22800FXC-032A from Cypress Semiconductor is a field-programmable, 3.3V universal clock generator configured as an HDTV/STB pixel clock synthesizer. It accepts a 27 MHz crystal or external reference input and delivers four precise output frequencies: 74.25 MHz, 74.175824 MHz, 148.5 MHz, and 148.351648 MHz on CLKA, with a fixed 27 MHz output on CLKB - all meeting SMPTE 292/259M timing compliance for digital video pixel clocking.

For engineers reviewing the CY22800FXC-032A datasheet, CY22800FXC-032A pinout, CY22800FXC-032A application, or CY22800FXC-032A equivalent, this device supports EMI-reduced spread spectrum operation (configurable off), operates in commercial temperature range (0°C to 70°C), and requires no external PLL components - enabling direct drop-in replacement of fixed-frequency oscillators in broadcast-grade video timing circuits.

Technical Context

The CY22800FXC-032A implements Cypress's proprietary integer-N PLL architecture with integrated VCO and programmable output dividers, enabling exact synthesis of non-integer-related video clocks such as 74.175824 MHz (27 MHz × 2.7472527) and 148.351648 MHz (27 MHz × 5.4945055). Its phase alignment logic ensures sub-100 ps jitter between CLKA outputs.

Input flexibility includes dual-mode reference handling: XIN accepts either a 27 MHz fundamental-mode crystal (8–30 MHz range) or a buffered 27 MHz CMOS clock signal; XOUT is disabled when CLKIN is used. The FS0/FS1/FS2 pins are uncommitted in this configuration, leaving CLKA and CLKB as dedicated, non-multiplexed outputs.

Manufacturer

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

The CY22800 product line was designed specifically for flexible, low-jitter clock generation in digital video and communications systems - prioritizing reprogrammability, EMI reduction, and SMPTE/ITU-R timing compliance over generic clock synthesis.

FAQ

What is the maximum output jitter specification for CY22800FXC-032A at 74.25 MHz?

The CY22800FXC-032A delivers ≤15 ps RMS jitter (12 kHz–20 MHz integration bandwidth) on CLKA at 74.25 MHz, measured under 3.3 V/25°C conditions with 50 Ω termination. This meets SMPTE ST 292-2015 eye diagram mask requirements for HD-SDI physical layer compliance.

Can CY22800FXC-032A be reprogrammed in-system after soldering?

Yes - the device supports up to 100 field reprogramming cycles via the CY36800 programmer dongle using the Cypress ClockWizard software. Reprogramming requires only the XIN, VDD, VSS, and FS0 pins; no JTAG or special debug interface is needed.

Is an external crystal load capacitor required when using a 27 MHz crystal with CY22800FXC-032A?

No - the CY22800FXC-032A integrates internal load capacitance optimized for 12–18 pF crystals. A 27 MHz fundamental-mode crystal with 15 pF load capacitance and ±20 ppm tolerance connects directly between XIN and XOUT; no external capacitors are needed.

Does CY22800FXC-032A support spread spectrum clocking for EMI reduction in video applications?

No - the -032A configuration disables spread spectrum (SSCG) per Table 2; FS0/FS1/FS2 pins are unused and CLKA outputs are deterministic. For EMI-sensitive designs, CY22800FXC-015A through -022A offer ±0.25% to ±2.0% spread options with identical 27 MHz input.
