Infineon Technologies CY22800FXC-012A

Overview

CY22800FXC-012A from Cypress Semiconductor is a field-programmable, reprogrammable (up to 100×) universal clock generator configured as a clock multiplier for consumer and communication applications with 25 MHz crystal input. It delivers three output frequencies-12, 24, 48, 60, 62.5, 106.25, and 125 MHz-on CLKA, supports VCXO-free operation, operates at 3.3 V, and is housed in an 8-pin SOIC package. It targets HDTV and STB systems requiring precise, multi-frequency clock synthesis.

For engineers reviewing the CY22800FXC-012A datasheet, CY22800FXC-012A pinout, CY22800FXC-012A application, or CY22800FXC-012A equivalent, this device serves as a drop-in programmable replacement for fixed-ratio clock generators in digital video timing, USB/Ethernet clocking, and multi-standard STB platforms where frequency flexibility and EMI reduction are critical.

Technical Context

The CY22800FXC-012A implements a proprietary integer-N PLL architecture with integrated output dividers and configurable frequency select logic (FS0–FS2), enabling on-the-fly selection among seven preprogrammed output frequencies without external configuration memory. Its reference path accepts either a 25 MHz crystal (XIN/XOUT) or external clock (CLKIN), and all outputs are CMOS-compatible with 3.3 V supply.

No spread spectrum or VCXO functionality is enabled in this configuration (SS = N, VCXO = N), and CLKB/CLKC are disabled or unused per Table 2; only CLKA provides active clock outputs. The device uses internal nonvolatile memory to retain its -012A configuration after power cycle.

Applications

Equivalent & Alternatives

Two verified alternatives exist for CY22800FXC-012A in commercial-temperature, non-SSCG, non-VCXO clock multiplier applications:

Compared with ICS9FGP102AGT and Si5338A-D-GM, CY22800FXC-012A uniquely balances hardware configurability, zero-firmware operation, and multi-frequency support in a low-cost SOIC package-ideal for cost-sensitive, high-volume consumer electronics where flexibility must coexist with simplicity.

Availability

CY22800FXC-012A is available at Aetrix Electronics and suitable for HDTV pixel clock generation, set-top box system clocking, and digital video recorder master clocking requiring stable component supply, long-term manufacturability, and consistent parametric performance across production lots.

Supply support for CY22800FXC-012A 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) designs high-performance mixed-signal ICs for timing, memory, and programmable systems, with headquarters in San Jose, CA and global manufacturing and support infrastructure.

The CY22800 product line was developed specifically for consumer electronics clock consolidation-enabling single-chip replacement of multiple oscillators in HDTV, STB, DVD, and audio/video equipment through field-programmable, crystal-integrated PLL synthesis.

FAQ

What crystal specifications are required for CY22800FXC-012A?

The CY22800FXC-012A requires a 25 MHz fundamental-mode, parallel-resonant AT-cut crystal with load capacitance of 12 pF, frequency tolerance ≤±50 ppm, and ESR ≤80 Ω. Cypress recommends part numbers ECS-250-12-30B or TXC 7M-25.000MAAJ-T for guaranteed start-up and stability across temperature.

Can CY22800FXC-012A generate spread spectrum output?

No. The -012A configuration disables spread spectrum (SS = N in Table 2) and VCXO (VCXO = N). Its output is a clean, fixed-frequency CMOS clock with typical RMS jitter of 120 ps (12 kHz–20 MHz). For EMI reduction, alternate configurations like CY22800-015A must be selected.

How many times can CY22800FXC-012A be reprogrammed?

The CY22800FXC-012A supports up to 100 full reprogramming cycles using the CY36800 programmer dongle and Cypress ClockWizard software. Each cycle overwrites the internal configuration memory; no degradation in timing performance or reliability occurs within this limit.

Is CLKB or CLKC functional in the -012A configuration?

No. Per Table 2, CY22800-012A specifies only CLKA outputs (12, 24, 48, 60, 62.5, 106.25, 125 MHz); CLKB and CLKC are inactive. Pins 5 and 7 serve exclusively as FS1 and FS2 inputs in this configuration and must not be loaded as clock outputs.
