Product Description
Broadcom 7nm 100GbE PAM-4 DSP Optical PHY (4:1) or (2:1) with Direct-Drive - BCM87101
The Broadcom BCM87101 is the industry’s lowest power single-chip 100GbE PAM-4 PHY transceiver capable of directly driving 106-Gb/s PAM-4 at 53 Gbaud, while supporting DR and FR optical links. The BCM87101 converts two lanes of 53 Gb/s (at 26-Gbaud PAM-4) or four lanes of 25-Gb/s NRZ from the system side into one lane of 106 Gb/s (at 53-Gbaud PAM-4) to drive next-generation high-density optical PAM-4 links inside QSFP28 and SFP-DD form-factor modules.
The BCM87101 device is available in a 9 mm × 8 mm,0.5-mm pitch, 255-ball BGA, RoHS-compliant package. The BCM87101 is pin-to-pin compatible with the BCM87103 device.
