Overview
Micrel, Inc.
ULTRA-LOW JITTER 2 × 2 CROSSPOINT SWITCH w/CML OUTPUTS AND INTERNAL I/O TERMINATION Precision Edge® Precision ESdY5g8e0®23U SY58023U FEATURES ■ Guaranteed AC performance over temperature and voltage: • >10.
7Gbps data throughput • <60ps tr/tf times • <285ps tpd (IN-to-Q) • <20ps skew ■ Low jitter: • <10pspp total jitter (clock) • <1psrms random jitter (data) • <10pspp deterministic jitter (data) ■ Crosstalk induced jitter: <0.
7psrms ■ Accepts an input signal as low as 100mV ■ Unique input termination and VT pin accepts DCcoupled and AC-coupled differential inputs: LVPECL, LVDS, and CML ■ 50Ω source terminated CML outputs ■ Fully differential inputs/outputs ■ Power supply 2.
5V ±5% and 3.
3V ±10% ■ Industrial –40°C to +85°C temperature range ■ Available in 16-pin (3mm × 3mm) MLF® package DESCRIPTION Precision Edge® The SY58023U is a 2.
5V/3.
3V precision, high-speed, fully differential CML 2 × 2 crosspoint switch.
The SY58023U is optimized to provide two identical output copies with less than 20ps of skew and ultra-low jitter.
It can route clock signals as fast as 6GHz or data up to 10.
7Gbps.
The differential input includes Micrel’s unique, 3-pin input termination architecture that allows the SY58023U to directly interface to LVPECL, LVDS, and CML differential signals (AC- or DC-coupled) as small as 100mV (200mVpp) without any level-shifting or termination resistor networks in the signal path.
The CML outputs features 400mV typical swing into 50Ω loads, and provide an extremely fast rise/fall time guaranteed to be less than 60ps.
The SY58023U operates from a +2.
5V ±5% supply or +3.
3V ±10% supply and is guaranteed over the full industrial temperature range (–40°C to +85°C).
For applications that require high speed dual CML switches, consider the SY58024U.
The SY58023U is part of Micrel’s high-speed, Precision Edge® product line.
