ADN4612ACPZ

ADN4612 is a 12 × 12 asynchronous, protocol agnostic, digital Crosspoint switch with 12 differential PECL-/CML-compatible inputs and 12 differential CML outputs. It is optimized for nonreturn-to-zero (NRZ) signalling with data rates of upto 11.3Gbps per port. Each port provides programmable input equalization, loss of signal (LOS) detection, programmable output swing, and output preemphasis/deemphasis. This device's nonblocking switch core implements a 12 × 12 crossbar and supports independent channel switching through the serial control interface. It has low latency and very low channel-to-channel skew. It is used in application such as fibre optic network switching, 10 gigabit ethernet over backplane 10GBASE-KR 802.3ap, XLAUI/CAUI (802.3ba), SONET OC-192/STM-64x, 1×, 2×, 4×, 8×, and 10× fibre channel etc.

• Multi time constant, programmable receive equalization
• Deterministic jitter (no channel) is 11ps p-p typical at (data rate = 10.3125Gbps)
• Random jitter (no channel) is 0.5ps rms typical at (VCC = VTTO1 = 2.5V)
• Double rank connection programming, 2-pin selectable connection maps
• Per lane lost of signal (LOS) detection, flexible output termination supply range (1.8V to 3.3V)
• DC- or AC coupled differential CML inputs and outputs, programmable CML output levels
• Load from EEPROM for automatic power-on ready operation
• Per lane input and output P/N pair inversion for routing ease
• Serial (I²C or SPI) control interface, operating temperature is -40°C to +85°C
• Package style is 88-lead lead frame chip scale [LFCSP-VQ]
