Pinout
DescriptionThe SCAN25100 is a 2457.6, 1228.8, and 614.4 Mbps serializer/deseralizer (SerDes) for high-speed bidirectional serial data transmission over FR-4 printed circuit board backplanes, balanced cables, and optical fiber. It is programmable though an MDIO interface as well as through pins, featuring configurable transmitter deemphasis, receiver equalization,speed rate selection, internal pattern generation/verification, and loop back modes.
The features of SCAN25100 can be summarized as:(1)Exceeds LV and HV CPRI voltage and jitter requirements; (2)2457.6, 1228.8, and 614.4 Mbps operation; (3)Integrated delay calibration measurement (DCM) directly measures T14 and Toffset delays to ± 800 ps; (4)DCM also measures chip and other delays to ±1200 psaccuracy; (5)Deterministic chip latency; (6)Independent transmit and receive PLLs for seamless RE synchronization; (7)Low noise recovered clock output; (8)Requires no jitter cleaning in single-hop applications; (9)>8 kV ESD on the CML IO, >7 kV on all other pins, >2 kV CDM; (10)Hot plug protection; (11)LOS, LOF, 8b/10b line code violation, comma, and receiver PLL lock reporting; (12)Programmable hyperframe length and start of hyperframe character; (13)Programmable transmit de-emphasis and receive equalization with on-chip termination; (14)1.8V or 3.3V compatible parallel bus interface; (15)100-pin TQFP package with exposed dap; (16)Industrial 40 to +85° C temperature range.
The absolute maximum ratings of SCAN25100 are:(1)Supply Voltage (AVDD18):-0.3V to +2.0V; (2)Supply Voltage (PVDD, IOVDD):-0.3V to +3.6V; (3)Supply Voltage (AVDD33):-0.3V to +3.6V; (4)LVCMOS Input Voltage:-0.3V to (IOVDD +0.5V); (5)LVCMOS Output Voltage:-0.3V to (IOVDD +0.5V); (6)MDC/MDIO/ADD[0:4],VSEL Input Voltage:-0.3V to (AVDD33 + 0.5V); (7)MDIO Output Voltage:-0.3V to (AVDD33 + 0.5V); (8)CML Receiver Input Voltage:-0.3V to (AVDD +0.3V); (9)CML Receiver Output Voltage:-0.3V to (AVDD +0.3V); (10)Junction Temperature:+125°C; (11)Storage Temperature:-65°C to +150°C; (12)Lead Temperature:Soldering, 1020 sec 235 °C,Lead-free +260°C flow is available.
