Infineon Technologies CY24206ZXC-4

Overview

CY24206ZXC-4 from Cypress Semiconductor is a MediaClock™ DTV/STB clock generator IC featuring an integrated PLL, 3.3V operation, and four selectable-frequency CMOS clock outputs-including REFCLK (27 MHz), CLK1 (up to 81.081 MHz), CLK2 (down to 24.725 MHz), and CLK3 (27–74.25 MHz)-designed for digital television and set-top box timing subsystems.

For engineers reviewing the CY24206ZXC-4 datasheet, CY24206ZXC-4 pinout, CY24206ZXC-4 application, or CY24206ZXC-4 equivalent, key selection criteria include frequency select logic (FS0–FS2), output enable control (OE), jitter performance (200 ps peak-to-peak), duty cycle stability (45–55%), and TSSOP-16 package compatibility with DTV reference clock distribution.

Technical Context

This device implements a single-loop PLL architecture with internal VCO operating up to 400 MHz, driven by a 27 MHz crystal input (XIN/XOUT). Output frequencies are derived via programmable dividers and multiplexed through three configurable clock channels plus a fixed 27 MHz REFCLK.

Frequency selection is controlled by three logic inputs (FS0, FS1, FS2), enabling eight discrete output combinations across CLK1, CLK2, and CLK3. All outputs meet CMOS voltage thresholds (VIH = 0.7×VDD, VIL = 0.3×VDD) and drive ≤15 pF loads with edge rates of 0.8–1.4 V/ns.

FAQ

What crystal specifications are required for CY24206ZXC-4?

The device requires a 27 MHz fundamental-mode AT-cut crystal with load capacitance of 12–18 pF, series resistance ≤40 Ω, and frequency tolerance ≤±20 ppm. The XIN/XOUT pins form a Pierce oscillator with internal gain; no external capacitors are needed if crystal manufacturer specifies built-in load caps.

How does OE pin behavior affect power consumption?

When OE is low, all clock outputs are disabled and static current drops to ≤5 µA. With OE high, typical supply current is 25 mA on AVDD/VDD and 20 mA on VDDL. This enables dynamic power gating during standby modes in STB remote-wake applications.

Can CY24206ZXC-4 generate non-integer multiples of 27 MHz?

Yes-via its programmable divider chain, it delivers exact frequencies including 81.081 MHz (27 × 3.003), 74.17582 MHz (27 × 2.74725), and 24.725 MHz (27 × 0.91574), matching DVB and ATSC standard pixel and sampling rates without external fractional-N synthesis.

Is the TSSOP-16 package compatible with reflow soldering per J-STD-020?

Yes-CY24206ZXC-4 uses lead-free (Pb-free) terminations qualified for IPC/JEDEC J-STD-020D.2 Level 3 moisture sensitivity (MSL-3), with peak reflow temperature of 260 °C and time above 217 °C ≤60 seconds, supporting standard SMT assembly lines.
