7 / 19 page GENNUM CORPORATION 522 - 28 - 05 7 of 19 PIN DESCRIPTIONS NUMBER SYMBOL LEVEL TYPE DESCRIPTION 1, 2, 3, 4, 6, 8, 9, 10, 11, 14, 15, 22, 23, 24, 25, 26, 27, 28, 29, 37, 38, 39, 40, 51, 52, 57, 58, 65, 66, 67, 68, 69, 70, 71, 77, 78, 82, 83, 84, 87, 88, 90, 92, 94, 95, 97, 99, 100, 101, 102, 103, 104, 107, 114, 115, 116, 118, 119, 121, 123, 125, 127, 128 NC No Connect. Leave these pins floating. 5 MCLADJ Analog Input Control Signal Input. Adjusts the maximum amount of cable for the equalizer (from 0m to the maximum cable length). Normally the output is muted (latched to the last state) when the set maximum cable length is exceeded. To achieve maximum cable length, this pin should be left open (floating). 7 CLI Analog Output Status Control Signal. The Cable Length Indication (CLI) signal provides approximate voltage representation of the amount of cable being equalized. 12 CD Digital Output Status Signal. The Carrier Detect indicator is used as an output status signal. When the CD output is low, the carrier is present and the data output is active. When the CD output is high, the carrier is not present and the data output is muted (latched to the last state). This indicates that the maximum cable length as set by MCLADJ has been reached. 13 EQO_VEE Power Input Negative Supply. Most negative power supply connection for Equalizer output buffer stage. 16 EQO_VCC Power Input Positive Supply. Most positive power supply connection for Equalizer output buffer stage. 17, 18 DDO, DDO ECL/PECL compatible Output Digital Data Output. Differential serial outputs. 50 Ω pull up resistors are included on chip. Note that these outputs are not cable drivers. Ensure that the trace length between the GS1545 and the GS1508 Cable driver is kept to a minimum and that a PCB trace characteristic impedance of 50 Ω is maintained between the GS1508 and the GS1545. 50 Ω end termination is recommended. 19 DDO_VEE Power Input Negative Supply. Most negative power supply connection for serial data output stage. 20 DDO_EN Power Input Control Signal Input. Used to enable or disable the serial output stage. If a loop through function is not required, then this pin should be tied to the most positive power supply voltage. When DDO_EN is tied to the most negative power supply voltage, the DDO, DDO outputs are enabled. When DDO_EN is tied to the most positive power supply voltage, the DDO, DDO outputs are disabled. 21 DDO_VCC Power Input Positive Supply. Most positive power supply connection for serial data output stage. 30, 31 SP_VCC Power Input Positive Supply. Most positive power supply connection for serial to parallel converter stage. |
