GC1122 Dual Channel 112Gb/s PAM-4 Linear Equalizer

The GC1122 provides a new option over the conventional choice between short, bulky copper cables and power-hungry, expensive optical interconnects by enhancing the signal integrity on copper cables while supporting 112Gbps PAM-4 signals. With dual-channel linear equalization, low input/output return loss, and high common mode rejection, the GC1122 is ideal for 112Gbps PAM-4 copper interconnects.

• Dual channel equalization
• Supports line rates up to 112Gbps PAM-4 (56Gbaud)
• Equalizes channel response beyond 30GHz
• Wideband equalization handles 64b/66b and 128b/130b coded data
• Works with PAM-4 (112Gb/s) signals
• Allows the receiver EQ to adapt and further equalize the signal
• Fully preserves effects of transmit pre-emphasis adjustments
• FEC compatible
• No time needed to adjust for dynamic rate changes
• Compact 2.7mm x 4.2mm 38-ball CSP, 0.5mm pitch
• Dual channel package ideal for top/bottom routing on SFP, SFP-DD, DSFP, QSFP, QSFP-DD, OSFP modules
• Operates off a single 3.3V power supply
• Each channel has independent equalization settings and standby control
• Lower active and standby power
