4 / 23 page GS7025 PRO-LINX™ Serial Digital Receiver Data Sheet 13813 - 7 October 2009 4 of 23 1.2 GS7025 Pin Descriptions Table 1-1: GS7025 Pin Descriptions Pin Number Name Type Description 1, 2 DDI/DDI I Digital data inputs (Differential ECL/PECL). 3, 44 VCC_75 I Power supply connection for internal 75Ω pullup resistors connected to DDI/DDI. 4, 8, 13, 22, 35 VCC I Most positive power supply connection. 5, 9, 14, 18, 27, 30, 33, 34, 37 VEE I Most negative power supply connection. 6, 7 SDI/SDI I Differential analog data inputs. 10 CD_ADJ I Carrier detect threshold adjust. 11, 12 AGC-, AGC+ I External AGC capacitor. Vcommon mode = 2.7V typ. 15, 16, 17 LF+, LFS, LF- I Loop filter component connection. 19 RVCO_RTN I RVCO Return. Frequency setting resistor return connection. 20 RVCO I Frequency setting resistor connection. 21 CBG I Internal bandgap voltage filter capacitor. 23, 25, 26 nc - No connect - Do not connect to power or ground. Leave floating. 24 RSV1 I Reserved pin 1. Always set HIGH. 28, 29 SCO/SCOO Serial clock output. SCO/SCO are differential current mode outputs and require external 75Ω pullup resistors. 31, 32 SDO/SDO O Equalized and reclocked serial digital data outputs. SDO/SDO are differential current mode outputs and require external 75Ω pullup resistors. 36 CLK_EN I Clock enable. When HIGH, the serial clock outputs are enabled. 38 COSC I Timing control capacitor for internal system clock. 39 LOCK O Lock indication. When HIGH, the GS7025 is locked. LOCK is an open collector output and requires an external 10kΩ pullup resistor. 40 SSI/CDO Signal strength indicator/Carrier detect. 41 A/D I Analog/Digital select. 42 MOD I 270 Mb/s modulus select - always set HIGH. 43 OEM_TEST O Output ‘Eye’ monitor test. Single-ended current mode output that requires an external 50Ω pullup resistor. This feature is recommended for debugging purposes only. If enabled during normal operation, the maximum operating temperature is rated to 60°C. For maximum cable length performance the OEM_TEST must be disabled. |
