The SY58025U features two ultra-fast, low jitter 2:1
differential muxes with a guaranteed maximum data or clock
throughput of 10.7Gbps or 7GHz, respectively.
Unique, patent-pending input isolation design
minimizes crosstalk
Ultra-low jitter design:
The SY58025U differential inputs include a unique,
internal termination design that allows access to the
termination network through a VT pin. The device easily
interfaces to different logic standards, both AC- and DC-
coupled, without external resistor-bias and termination
networks. The result is a clean, stub-free, low jitter interface
solution. The differential CML output is optimized for 50ý
environments with internal 50ý source termination and a
400mV output swing.

Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs
accept AC- or DC-coupled differential signals as small as 100mV. Each pin of a pair
internally terminates to a VT pin through 50ý. Note that these inputs will default to an
indeterminate state if left open. Unused differential input pairs can be terminated by
connecting one input to VCC and the complementary input to GND through a 1ký resistor.
The VT pin is to be left open in this configuration. Please refer to the “Input Interface
Applications” section for more details.

Bank A, Bank B Input Channel Select (TTL/CMOS): These TTL/CMOS-compatible inputs
select the inputs to the multiplexers. These inputs are internally connected to a 25ký
pull-up resistor and will default to a logic HIGH state if left open. Input switching threshold
is VCC/2.

Notes:
1. Permanent device damage may occur if the ratings in “Absolute Maximum Ratings” section are exceeded. This is a stress rating only and functional
operation is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratings
conditions for extended periods may affect device reliability.
2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
3. Due to the limited drive capability, use for input of the same package only.
4. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the device’s most negative potential (GND) on the PCB. Ψ uses 4-
