PinNumber PinName
PinFunction
17, 15,
IN0, /IN0
Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs accept
10, 8,
IN1, /IN1
AC or DC-coupled signals as small as 100mV. Each pin of a pair internally terminates to a VT pin
4, 2,
IN2, /IN2
through 50. Note that these inputs will default to an indeterminate state if left open. Please refer to
41, 39
IN3, /IN3
the “Input Interface Applications” section for more details.
16, 9,
VT0, VT1
Input Termination Center-Tap: Each side of the differential input pair terminates to a VT pin. The VT
3, 40
VT2, VT3
pins provide a center-tap to a termination network for maximum interface flexibility. See “Input
Interface Applications” section for more details.
14,
VRef_AC0
Reference Voltage: This output biases to VCC–1.2V. It is used when AC coupling the inputs.
11,
VRef_AC1
Connect VRef-AC output pin to the VT input pin. Bypass each VRef-AC pin with a 0.01F low ESR
1,
VRef_AC2
capacitor to VCC. See “Input Interface Applications” section for more details.
42
VRef_AC3
18
SIN0
These single-ended TTL/CMOS-compatible inputs address the data inputs. Note that these inputs
19
SIN1
are internally connected to a 25k pull-up resistor and will default to a logic HIGH state if left open.
38
SOUT0
These single-ended TTL/CMOS-compatible inputs address the data outputs. Note that these inputs
37
SOUT1
are internally connected to a 25k pullup resistor and will default to a logic HIGH state if left open.
5
CONF,
These single-ended TTL/CMOS compatible inputs control the transfer of the addresses to the
7
LOAD
internal multiplexers. See “Address Tables” and “Timing Diagram” sections for more details. Note
that these inputs are internally connected to a 25k pull-up resistor and will default to a logic HIGH
state if left open.
Configuration Sequence
1. Load: Loads configuration into buffer, while Configuration Buffer holds existing switch configuration.
2. Configuration: Loads new configuration into the Configuration Buffer and updates switch configuration.
Buffer Mode
The SY58040U defaults to buffer mode (IN-to-Q) if the load and configuration control signals are floating.
23, 24,
Q0, /Q0,
Differential Outputs: These CML output pairs are the outputs of the device. Please refer to the truth
26, 27,
Q1, /Q1,
table below for details. Unused output pairs may be left open. Each output is designed to drive

400mV into 100 across the pair, or 50 to VCC.
32, 33
Q3, /Q3,
6, 22, 25,
VCC
Positive power supply. Bypass with 0.1F//0.01F low ESR capacitors and place as close to each
28, 31, 34
VCC pin.
12, 13, 20, 21,
GND,
Ground. GND and EPad must both be connected to most negative potential of chip ground.
