The ten channels consist of four high speed channels (A, B, C, and D), four average speed channels (E, F, G, and H), and two channels with paraphase output (RF+ and RF-). The RF channels output is sum of A + B + C + D channels with identical weights. Low noise operation enables data recovery at very low signal levels. The SP8062 has three logic inputs for gain control, one of them operating as TTL compatible (Gain 1), and two other operating as three state logic inputs (Gain 2 and Gain 3). The allowable logic states are used to select 10 gain factors and a sleep mode (see table 4). In sleep mode all channels are in tri-state condition. The SP8062 is manufactured with an advanced 10GHz BICMOS technology. Rev 1.7 (01-16-04): SP8062 – High Speed 10 Channel PDIC SIPEX RESERVES THE RIGHT TO MAKE CHANGES TO THIS DATASHEET.

High quality, low series resistance ceramic 0.1uF bypass capacitors should be used at the Vcc and Vs pins (pins 1 and 16). These capacitors must be located as close to the pins as possible. The traces connecting the pins and the bypassing capacitors must be kept short and should be made as wide as possible.
