Infineon Technologies CY22800FXC-009A

Overview

CY22800FXC-009A from Cypress Semiconductor is a field-programmable universal clock generator configured as a clock multiplier for consumer and communication applications with 20 MHz crystal input, delivering seven fixed output frequencies (33.33, 66.66, 50, 75, 80, 100, and 133.33 MHz) on CLKA, operating at 3.3 V, in an 8-pin SOIC package, and supporting commercial temperature range (0°C to 70°C).

For engineers reviewing the CY22800FXC-009A datasheet, CY22800FXC-009A pinout, CY22800FXC-009A application, or CY22800FXC-009A equivalent, this device serves as a reprogrammable, spread-spectrum-capable PLL-based clock synthesizer optimized for HDTV, STB, and digital video recorder timing subsystems requiring stable multi-frequency outputs from a single reference.

Technical Context

The CY22800FXC-009A implements a proprietary integer-N PLL architecture with integrated output dividers and programmable frequency select logic, enabling fixed-ratio multiplication of a 20 MHz crystal input to generate seven discrete output frequencies on CLKA without external components. Its internal VCXO control path remains inactive (VCXO = No), and spread spectrum is disabled (SS = No), confirming deterministic, low-jitter clock synthesis.

Pin functionality is configuration-dependent: FS0/VCXO (Pin 3), FS1 (Pin 5), and FS2 (Pin 7) serve as frequency select inputs in this variant but are unused since all outputs are preconfigured; CLKB and CLKC default to REFOUT or disabled per Table 2, and XOUT (Pin 8) is a no-connect when using crystal input.

FAQ

Can CY22800FXC-009A be reprogrammed in-circuit?

Yes - CY22800FXC-009A supports up to 100 field reprogramming cycles using the CY36800 programmer dongle and Cypress's ClockWizard software. Reprogramming requires only VDD, VSS, FS0, FS1, and FS2 pins; no dedicated programming interface or bootloader is needed. The device retains configuration through power cycles without external nonvolatile memory.

What is the maximum output drive strength for CLKA?

CLKA delivers CMOS-level outputs with 8 mA sink/source capability at 3.3 V, supporting fanout to up to 10 standard CMOS loads or one LVDS receiver with appropriate termination. Rise/fall times are specified at ≤3 ns (20%–80%) under 50 pF load, and output skew between CLKA and CLKB is ≤150 ps over temperature and voltage.

Does CY22800FXC-009A require external loop filter components?

No - the CY22800FXC-009A integrates all PLL loop filter components internally. No external capacitors or resistors are required for lock acquisition or stability. This eliminates tuning effort and board space typically needed for discrete PLL filters, and ensures consistent jitter performance across production units.

Is the 20 MHz crystal requirement rigid, or can it accept a 20 MHz clock signal?

The CY22800FXC-009A is configured exclusively for 20 MHz crystal input (XIN/XOUT mode); it does not support external 20 MHz clock injection on XIN. The internal oscillator circuit is tuned for crystal resonance - applying a buffered clock signal will prevent startup or cause unstable locking due to missing Pierce oscillator bias and load capacitance.
