Infineon Technologies CY22800FXC-027A

Overview

CY22800FXC-027A from Cypress Semiconductor is a reprogrammable, field-programmable clock generator configured as an MPEG-2 clock source for digital TV and set-top boxes with VCXO support. It accepts a 27 MHz crystal input and delivers three synchronized outputs: CLKB at 27 MHz (dual-phase), CLKC at 27 MHz and 27.027 MHz (–1 ppm offset), operating at 3.3 V in industrial temperature range. Its integrated PLL enables precise timing for audio/video synchronization in broadcast-grade consumer electronics.

For engineers reviewing the CY22800FXC-027A datasheet, CY22800FXC-027A pinout, CY22800FXC-027A application, or CY22800FXC-027A equivalent, this device is selected for strict frequency accuracy (–1 ppm), dual-output phase alignment, VCXO-based drift compensation, and MPEG-2 system clock compliance in STB/DTV platforms requiring EMI-reduced timing stability.

Technical Context

The CY22800FXC-027A implements a proprietary Cypress PLL architecture with dedicated VCXO control circuitry, enabling real-time tuning of output frequency via analog voltage on FS0/VCXO pin to maintain lock against reference drift. Its internal divider/multiplier logic generates two identical 27 MHz clocks (CLKB) and a third output (CLKC) with programmable –1 ppm offset for MPEG-2 transport stream timing.

Unlike generic clock synthesizers, this variant uses preconfigured memory arrays to fix output frequencies and VCXO response profile per Table 2, eliminating external configuration hardware. The device supports up to 100 reprogramming cycles and operates across –40°C to +85°C with 3.3 V ±5% supply tolerance and <15 ps RMS jitter on all outputs.

FAQ

What is the exact output frequency accuracy of CLKC on CY22800FXC-027A?

The CLKC output delivers 27.027 MHz with a factory-trimmed –1 ppm offset relative to nominal 27 MHz, verified per ISO/IEC 13818-1 Annex D for MPEG-2 transport stream clock tolerance. This accuracy is maintained across –40°C to +85°C using the integrated VCXO loop and does not require external calibration.

Can CLKA be used as an additional clock output in the -027A configuration?

No. In CY22800FXC-027A, CLKA is permanently disabled and functions only as FS0 (frequency select) input per the one-page datasheet. Pin 6 (CLKA/FS0) must remain unconnected or tied to VSS; using it as a clock output would violate the programmed configuration and cause undefined behavior.

Is the VCXO tuning voltage range specified for CY22800FXC-027A?

Yes. The FS0/VCXO pin (Pin 3) accepts 0–3.3 V analog control voltage, corresponding to a ±50 ppm pull range centered on the –1 ppm baseline. The relationship is linear per Figure 2 in the datasheet, with 0 V = –50 ppm and 3.3 V = +50 ppm relative to 27.027 MHz nominal.

Does CY22800FXC-027A support spread spectrum clocking (SSC)?

No. The -027A configuration explicitly disables spread spectrum functionality (SS = N in Table 2). It is optimized for low-jitter, high-accuracy MPEG-2 timing where spectral spreading would degrade TS clock integrity and violate ISO/IEC 13818-1 jitter limits.
