Infineon Technologies CYV15G0403DXB-BGC

Overview

CYV15G0403DXB-BGC from Cypress Semiconductor is an independent-clock quad-channel HOTLink II™ transceiver IC for high-speed serial interconnects in broadcast video and professional media systems. It supports SMPTE-259M (270 Mbps) and SMPTE-292M (1.485 Gbps) compliance per EG34-1999 pathological test requirements, operates at 195–1500 MBaud per channel, delivers up to 12 Gbps aggregate throughput, and features dual PECL-compatible differential I/O per channel with internal DC restoration.

For engineers reviewing the CYV15G0403DXB-BGC datasheet, CYV15G0403DXB-BGC pinout, CYV15G0403DXB-BGC application, or CYV15G0403DXB-BGC equivalent, this device is selected for multi-standard serial link design where per-channel rate independence, 8B/10B encoding, low-latency framing, and JTAG/BIST validation are required in SMPTE-compliant infrastructure.

Technical Context

The CYV15G0403DXB-BGC implements four fully independent transmit/receive channels, each with its own reference clock input (REFCLKA–D), enabling simultaneous operation at different data rates-e.g., one channel at 270 MBaud (SD-SDI), another at 1485 MBaud (HD-SDI). Each channel integrates a programmable 8B/10B encoder/decoder, a ×10 serializer/deserializer, and a Clock and Data Recovery (CDR) PLL with no external components.

Its MultiFrame™ Receive Framer supports bit/byte alignment, comma detection (K28.5), and selectable low-latency mode; the parallel LVTTL interface allows synchronous or recovered-clock data capture, while per-channel Link Quality Indicators provide analog/digital signal detect status for real-time link health monitoring.

FAQ

Is CYV15G0403DXB-BGC pin-compatible with CYW15G0403DXB-BGC?

Yes-both variants share identical 256-ball BGA footprint, pin assignment, and electrical interface. The difference is functional: CYW supports 1540 MBaud and OBSAI-RP3, while CYV is certified for SMPTE-259M/292M pathological testing. No PCB redesign is needed when substituting within rated speed limits.

Does CYV15G0403DXB-BGC require external termination resistors on PECL lines?

No-its differential PECL-compatible outputs (OUTx1±/OUTx2±) are source-matched to 50 Ω and do not require external bias or termination resistors. Inputs (INx1±/INx2±) accept standard PECL swing and include internal DC restoration, eliminating AC-coupling capacitor dependency in many layouts.

Can the 8B/10B encoder be disabled for custom encoding schemes?

Yes-the encoder/decoder can be bypassed via configuration bits (ENCBYPx, DECBYPx). When disabled, the device passes raw 8-bit parallel data directly to serializer/deserializer, supporting proprietary or scrambled protocols while retaining CDR, framing, and BIST functionality.

What is the role of the MultiFrame™ Receive Framer's low-latency mode?

Low-latency mode disables multi-byte alignment buffering, reducing receive path delay to ≤3 character periods. This is essential for real-time video processing pipelines where end-to-end latency must stay below 1 video line period-e.g., in live production switchers or AR graphics overlays.
