Infineon Technologies CYV15G0204TRB-BGC

Overview

CYV15G0204TRB from Cypress Semiconductor Corporation is a second-generation HOTLink II™ dual serializer and dual reclocking deserializer IC for SMPTE 259M/292M video applications. It provides independent 195–1500 Mbps serial links per channel, supports simultaneous full/half-rate operation at different signaling rates (e.g., 1.485 Gbps and 1.485/1.001 Gbps), and integrates PLLs with no external components. Used in multi-format SDI routers and camera control units.

For engineers reviewing the CYV15G0204TRB datasheet, CYV15G0204TRB pinout, CYV15G0204TRB application, or CYV15G0204TRB equivalent, key selection criteria include dual-channel rate independence, integrated CDR PLLs, PECL-compatible differential I/O with internal termination, BIST-enabled at-speed link validation, and SMPTE compliance without external clock conditioning.

Technical Context

The CYV15G0204TRB implements two fully independent transmit channels (TXA/TXB) and two independent receive/reclocker channels (RXC/RXD), each with dedicated PLLs, phase-align buffers, and BIST engines. Each TX channel accepts 10-bit LVTTL parallel data synchronized to REFCLKx± or TXCLKx and serializes at 10× or 20× that rate.

Each RX channel employs a fully integrated Clock and Data Recovery (CDR) PLL to reconstruct timing from PECL-compatible differential inputs (INC1±/INC2±), then deserializes to 10-bit parallel outputs (RXDC[9:0]/RXDD[9:0]) while simultaneously reclocking and retransmitting via ROUTC1±/ROUTC2± and ROUTD1±/ROUTD2±.

FAQ

What clocking configurations does CYV15G0204TRB support for independent channel operation?

The device supports full-rate (REFCLKx± = character rate) and half-rate (REFCLKx± = half-character rate) modes per channel. Each TX/RX channel uses its own REFCLKx±, allowing simultaneous operation at different rates-e.g., REFCLKA± at 148.5 MHz (1.485 Gbps) and REFCLKB± at 100.1 MHz (1.001 Gbps). TXCKSELx selects whether REFCLKx± or TXCLKx drives the parallel interface.

How does the built-in Link Quality Indicator (LQI) function in real-world deployment?

LQI provides two independent outputs: analog signal detect (ASD) asserts when valid differential amplitude (>100 mVpp) is present, and digital signal detect (DSD) asserts only when both valid amplitude and correct data transition density are confirmed. This enables early warning of marginal cable or connector degradation before bit errors occur, critical for broadcast uptime.

Can CYV15G0204TRB operate with single-ended LVTTL reference clocks instead of differential PECL?

Yes. REFCLKA± and REFCLKB± accept single-ended LVTTL inputs: connect the clock source to either REFCLKx+ or REFCLKx− and leave the complementary pin floating. The internal receiver automatically adapts. However, differential LVPECL is recommended for noise immunity in high-density video chassis environments.

What is the role of the Phase-Align Buffer (PAB) and how is it managed during dynamic rate changes?

The PAB absorbs phase drift between REFCLKx± and TXCLKx. When TXCLKx phase shifts beyond ±180°, TXERRx asserts. To recover, write PABRSTx = 0 via the configuration interface-this resets the buffer and reinitializes alignment. This mechanism enables seamless switching between asynchronous clock domains without data loss or manual resynchronization.
