Pin Functions

PIN I/O DESCRIPTION
NAME NUMBER
ALARM L8 O CMOS output for ALARM condition. The ALARM output functionality is defined through the config7 register. Default polarity is active high, but can be changed to active high via config0 alarm_out_pol control bit. If not used it can be left open.
AMUX0 H3 I/O Analog test pin for SerDes, Lane 0 to Lane 3. It can be left open if not used.
AMUX1 E3 I/O Analog test pin for SerDes, Lane 4 to Lane 7. It can be left open if not used.
ATEST K9 I/O Analog test pin for DAC, references and PLL. It can be left open if not used.
DACCLKP A10 I Positive LVPECL clock input for DAC core with Vcm = 0.5V. It can be PLL reference clock or external DAC sampling rate clock. If not used, DACCLK is self-biased with 100mV differential at Vcm = 0.5V.
DACCLKN A9 I Complementary LVPECL clock input for DAC core. (see the DACCLKP description)
EXTIO F10 I/O Used as external reference input when internal reference is disabled through config27 extref_ena = ‘1’. Used as internal reference output when config27 extref_ena = ‘0’ (default). Requires a 0.1 μF decoupling capacitor to analog GND when used as reference output. It can be left open if not used.
GND A12, F12, G12, M12, A11, B11, C11, D11, E11, F11, G11, H11, J11, K11, L11, M11, C8, D8, E8, F8, G8, H8, J8, E7, F7, G7, H7, E6, F6, G6, H6, A5, B5, E5, F5, G5, H5, A4, B4, M4, B3, C3, L3, B2, C2, D2, E2, H2, J2, K2, L2 I These pins are ground for all supplies.
IFORCE C5 I/O Analog test pin for on chip parametric. It can be left open if not used.
