Infineon Technologies CYP15G0403DXB-BGXI

Overview

CYP15G0403DXB-BGXI from Cypress Semiconductor is a quad-channel, independent-clock HOTLink II™ transceiver IC for high-speed serial interconnects. It supports 195–1500 MBaud per channel, delivers up to 12 Gbps aggregate throughput, features dual PECL-compatible differential I/O per channel, integrated 8B/10B encoding/decoding, and operates from a single 3.3V supply. It is used in multi-protocol telecom aggregation equipment requiring simultaneous ESCON, DVB-ASI, and SMPTE-259M-compliant links.

For engineers reviewing the CYP15G0403DXB-BGXI datasheet, CYP15G0403DXB-BGXI pinout, CYP15G0403DXB-BGXI application, or CYP15G0403DXB-BGXI equivalent, key selection criteria include per-channel rate independence, embedded PLL clock recovery, BIST-enabled at-speed link validation, and compatibility with fiber-optic modules and backplane traces.

Technical Context

The CYP15G0403DXB-BGXI implements four fully autonomous transmit/receive channels, each with dedicated reference clock inputs (REFCLKA–D±), independent PLL-based clock and data recovery, and selectable input/output clocking modes (local or recovered). Each channel processes 8-bit parallel data via configurable 8B/10B encoding or bypasses encoding for pre-scrambled streams.

Its receive path includes MultiFrame™ framer logic supporting comma detection (K28.5), bit/byte alignment, and low-latency framing options; its transmit path integrates phase-align buffers, serializer multipliers (×10 or ×20), and source-matched PECL drivers eliminating external bias resistors. All channels support JTAG boundary scan and per-channel Link Quality Indicator (analog/digital signal detect).

FAQ

Does CYP15G0403DXB-BGXI support 8B/10B encoding bypass?

Yes. The device allows full bypass of the 8B/10B encoder/decoder via the DECBYP[A..D] and ENCBYP[A..D] control bits, enabling transport of externally scrambled or pre-encoded data - a requirement for CPRI v4.1 and OBSAI-RP3 implementations where encoding is handled upstream.

What is the function of the two differential serial I/O pairs per channel?

Each channel has two independent PECL-compatible differential pairs (e.g., INA1±/INA2± and OUTA1±/OUTA2±) to support redundant or load-balanced serial links, or to carry separate data/command streams - such as primary payload + sideband control in broadcast router applications.

How does the MultiFrame™ Receive Framer improve video transport reliability?

The MultiFrame™ Framer provides configurable comma detection (K28.5), byte alignment, and low-latency framing modes - ensuring deterministic, frame-accurate recovery of SMPTE-292M HD-SDI streams even under bursty jitter conditions common in studio distribution networks.

Is JTAG boundary scan supported on all four channels simultaneously?

Yes. The integrated IEEE 1149.1 JTAG controller supports full boundary scan of all I/O pins, including all 16 serial differential pairs, 32 parallel data lines, and control signals - enabling system-level interconnect validation without channel arbitration or time-division multiplexing.
