• Manufacturer Part Number: max9963bjccq-td
• Description: Quad Low-power 500mbps Ate Driver/comparator
• Manufacturer: Maxim Integrated Products, Inc.

A CMOS-compatible serial interface controls the
MAX9963/MAX9964 modes (Figure 6). Control data flow
into an 8-bit shift register (MSB first) and are latched
when CS is taken high, as shown in Figure 5. Data from
the shift register are then loaded into any or all of a
group of four quad latches, determined by bits D4
through D7, as indicated in Figure 6 and Table 4. The
quad latches contain the 4 mode bits for each channel
of the quad pin driver. The mode bits, in conjunction
with external inputs DATA_ and RCV_, manage the fea-
tures of each channel, as shown in Tables 1 and 2. RST
sets LLEAK=1 for all channels, forcing them into low-
leakage mode. All other bits are unaffected. At power-
up, hold RST low until V

These devices require heat removal under normal cir-
cumstances through the exposed pad, either by solder-
ing to circuit board copper (MAX9964) or by use of an
external heat sink (MAX9963). The exposed pad is
electrically at V
