TxCLKIN+/- are the inverting and non-inverting LVDS transmit clock input TxCLKIN- 38 pins. TxIN[4:0]+/- 39, 40, I, LVDS Serializer input data. TxIN[4:0]+/- are the inverting and non-inverting LVDS serializer input data 41, 42, pins. 43, 44, 45, 46, 47, 48 LVCMOS Control Pins DC_B 5 I, DC-balance and Remote Sense pins. See Device Configuration section DEVICE RS 6 LVCMOS CONFIGURATION for device behavior. DE_EMPH0 9 I, DE_EMPH0, DE_EMPH1 select the output de-emphasis level. These pins are internally pull- DE_EMPH1 10 LVCMOS down. 00: Off 01: Low 10: Medium 11: Maximum TXOUT1_EN 12 I, DS32ELX0421 ONLY. When held high, redundant output TxOUT1+/- is enabled. This pin must LVCMOS be tied high when using TxOUT1+/-. RESET 30 I, When held low, reset the device. LVCMOS 0 = Device Reset 1 = Normal operation LOCK 31 O, Lock indication output. The input data on TxIN[0:4]+/- pins is ignored when LOCK pin is high. LVCMOS SMBus Interface SCK 33 I/O, SMBus compatible clock. SMBus SDA 32 I/O, SMBus compatible data line. SMBus SMB_CS 34 I, SMBus SMBus chip select. When held high, SMBus management control is enabled. Other GPIO0 3 I/O, Software configurable I/O pin. LVCMOS GPIO1 4 I/O, Software configurable I/O pin. LVCMOS GPIO2 11 I/O, Software configurable I/O pin. LVCMOS NC 2, 8, 12, 13, Misc. No Connect, for DS32EL0421 19, 20, 21, 22, 23, 24, 29 2, 8, 13, 21, Misc. No Connect, for DS32ELX0421 22, 23, 24, 29 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. 4 Submit Documentation Feedback Copyright © 2008–2013, Texas Instruments Incorporated Product Folder Links: DS32EL0421 DS32ELX0421 |
