Infineon Technologies CYP15G0403DXB-BGC

Overview

CYP15G0403DXB-BGC from Cypress Semiconductor is an independent-clock quad HOTLink II™ transceiver IC for high-speed serial interconnects, supporting 195–1500 MBaud per channel with dual PECL-compatible differential I/O per channel, 8B/10B encoding/decoding, and integrated PLL-based clock recovery. It enables multi-protocol backplane and fiber-optic links in telecom aggregation equipment.

For engineers reviewing the CYP15G0403DXB-BGC datasheet, CYP15G0403DXB-BGC pinout, CYP15G0403DXB-BGC application, or CYP15G0403DXB-BGC equivalent, key selection criteria include per-channel independent reference clocking, aggregate 12 Gbps throughput, JTAG boundary scan support, BIST-enabled at-speed link validation, and compliance with ESCON, DVB-ASI, SMPTE-259M/292M, and Gigabit Ethernet physical layer requirements.

Technical Context

This transceiver implements four fully independent serial channels, each with dedicated transmit PLL, receive clock-and-data-recovery (CDR) PLL, and configurable 8B/10B encoder/decoder. Each channel accepts LVTTL parallel data (8-bit or pre-encoded 10-bit) and outputs dual PECL-compatible differential serial streams at 10× or 20× the local reference clock rate.

The device integrates MultiFrame™ framer logic for bit/byte alignment, comma detection (K28.5), and low-latency framing modes; supports synchronous LVTTL parallel interface with selectable input/output clock domains; and includes per-channel analog/digital signal detect, link quality monitoring, and built-in self-test (BIST) pattern generation/checking for end-to-end path validation.

FAQ

Is CYP15G0403DXB-BGC pin-compatible with CYV15G0403DXB-BGC and CYW15G0403DXB-BGC?

Yes - all three variants share identical 256-ball BGA footprint, pin assignment, and electrical interface specifications. Differences are limited to internal firmware configuration and compliance validation; no PCB redesign is required when substituting within the same package option.

Does CYP15G0403DXB-BGC support 8B/10B encoding bypass for externally scrambled data?

Yes - the integrated 8B/10B encoder/decoder can be disabled per channel via configuration registers, allowing direct transport of pre-scrambled or pre-encoded 10-bit data across the serial link without modification.

What clocking options are available for the parallel interface?

The parallel I/O supports multiple clocking modes: transmit data may be clocked by local REFCLKx or TXCLKx; receive data may be output relative to recovered RXCLKx or local REFCLKx - enabling synchronous, source-synchronous, or elastic buffer-based timing architectures.

How is link quality monitored per channel?

Each channel provides two independent status signals: analog signal detect (ASD) confirms presence of valid differential amplitude, and digital signal detect (DSD) validates lock to incoming data stream - both accessible via dedicated LVTTL pins (e.g., RXSTA[2:0]) for real-time diagnostics.
