6 / 71 page GS1559 HD-LINX™ II Multi-Rate Deserializer with Loop-Through Cable Driver Data Sheet 30572 - 8 July 2008 6 of 71 1.2 Pin Descriptions Table 1-1: Pin Descriptions Pin Number Name Timing Type Description A1 LF Analog Output Control voltage to external Voltage Controlled Oscillator. Nominally +1.25V DC. A2 VCO_VCC – Output Power Power Supply for the external Voltage Controlled Oscillator. Connect to pin 7 of the GO1555/GO1525*. This pin is an output. Should be isolated from all other power supplies. *For new designs use the GO1555. A3 VCO_GND – Output Power Ground reference for the external Voltage Controlled Oscillator. Connect to pins 2, 4, 6, and 8 of the GO1555/GO1525*. This pin is an output. Should be isolated from all other grounds. *For new designs use the GO1555. A4, A5 VCO, VCO Analog Input Differential inputs for the external VCO reference signal. For single ended devices such as the GO1555/GO1525*, VCO should be AC coupled to VCO_GND. VCO is nominally 1.485GHz. *For new designs use the GO1555. A6, B5, B6, C4, C5, D2, D3, D7, E3, E7, F2, F3, F7, G2, G3, G7, H3, J2, J3, J4, NC – – No Connect. A7 PCLK – Output PARALLEL DATA BUS CLOCK Signal levels are LVCMOS/LVTTL compatible. HD 20-bit mode PCLK = 74.25MHz or 74.25/1.001MHz HD 10-bit mode PCLK = 148.5MHz or 148.5/1.001MHz SD 20-bit mode PCLK = 13.5MHz SD 10-bit mode PCLK = 27MHz A8, E8, K8 IO_VDD – Power Power Supply connection for digital I/O buffers. Connect to +3.3V DC digital. |
